Fish of Fury

This is why people hated Tau players with a burning hatred rivalling the rage Angry Marines have for Cultist-chan. Every single bad joke made about Tau players forevermore is pretty much entirely justified due to how annoying, stupid, and prevalent this was until the ruleset and codex updates.

Even veteran Tau players (the ones that aren't faggots anyway) openly criticized this bullshit after it swept tournament after tournament after tournament. Most players that aren't retarded are glad this shit is gone, and cheerfully tell those who used this trick to enjoy their AIDS.

How it Worked

Previously, the Devilfish transport for the Tau counted as a skimmer at all times. It was also very large for a transport (a Devilfish is notably longer than a Chimera, for example). The general gist is that a player would park 2 devilfish close togther in a chevron formation, have the troops disembark, and fire from a basically assault-proof bunker caused by the pair of Devilfish. Units couldn't charge around the 'Fish (because they were too big and due to the rules on assaults), and couldn't assault the 'Fish itself or hit it with Meltabombs (because it was a Skimmer).

The tactic was insanely powerful, though not unbeatable - canny players knew the disadvantages Devilfish had and would ergo target them with lots of heavy weaponry - but because of Displacement Fields, Devilfish often proved surprisingly difficult for many factions - especially those with limited anti-tank options, such as the Orks, Tyranids, and Necrons. The 5th-ed tactic of rushing in a METAL BOX and unloading Meltaguns into the fish was suicidal, because 4th ed brought us the chance to destroy vehicles with glancing hits - and from 2 full formations of Fire Warriors (not to mention the Devilfish transports if they survived) would mean a mulched Rhino and the Marines inside facing down 30+ S5 shots in rapid fire range. And that's assuming that the player wasn't a cockbag and included a Pulse Carbine on the Shas'ui just so he could pin your squad as part of the bargain.

The only reliable tricks to beat Fish of Fury were ironically deployed by Chaos, the Imperial Guard, the Inquisition, and the SPESS MEHREENS. These four factions either had ways to get big ugly close-combat troops right into the enemy's midst (Chaos, Inquisition, Space Marines), Artillery which could fuck up the shit of the entire Devilfish-Bunker (Imperial Guard, Inquisition, Space Marines), or big fucking ordnance weapons that could render the tactic a moot point (all of the above). Even for these factions, however, the tactic was infuriatingly hard to stop; one Devilfish-bunker could dictate the flow of an entire battle, and attempts to destroy the damned bunker would invariably met by Stealthsuit and Crisis Suit teams ambushing your forces, markerlights showering everything, and of course, railguns.

This naturally led to thread after thread of "HOW THE FUCK DO I STOP FISH OF FURY" and "FUCKING NERF MECH TAU" threads on every Games Workshop official forum (and, of course, /tg/). The bullshit saw no signs of abatement and saw use with just about every Tau army in the official tournaments. The hate for it was not limited to non-Tau players, either: It was so prevalent and so hated that large numbers of Tau players went to increasingly-absurd lengths just to avoid any association whatsoever with it; players would openly footslog Fire Warriors just so they would not be associated with Devilfish-induced cheese.

The tactic became a self-sustaining nuclear fireball of fail and derp. Like several equally-broken things before it, this thing needed to be fixed before it managed to warp the metagame even further - and in a surprisingly uncharacteristic maneuver for Games Workshop, they updated the Tau codex, which was easily the youngest of the set. This update, and the one succeeding it, were what finally led to the tactic's demise.

Suddenly Updates

The bullshit finally stopped with the new ruleset and how it covered line-of-sight, paired with the fact that the Devilfish now automatically lands if it's immobile for a turn, losing skimmer status. Then 5E rules said you can assault skimmers anyway. The new armor rules (glancing hits can't destroy a vehicle) also helped. A textbook example of how occasionally Games Workshop gets its head in the game and stops sucking for a few minutes, it's now possible to blow the fucking things up with Meltabombs and the onslaught of RAGE brought about by this tactic is now a thing of the past, making the tactic only about as effective as Mechanized Guard Chimera attacks (which was frankly how it fucking should have always been).

...Of course, the TLOS in 5th Edition means you can now do this with Rhinos and smoke instead, so it's apparently OK for the Space Marines to do it. THE ENEMY HIDES BEHIND METAL BOXES!! THE COWARDS! THE FOOLS!!!
