Editing Reincarnation (section)

==== No Fun Allowed ====
# In some editions, it's flat-out impossible to Reincarnate into something other than normal humanoid. Therefore, it's both not useful to you ''and'' not harmful to BBEG - basically useless.
## In 5e, it works only on humanoid, and can turn only into basic humanoid you start the game as.
## In Pathfinder and 3.5e, it only turns creature into same type. Humanoid into humanoid, beast into beast, dragon into dragon, etc. There are lizardfolk/troglodyte, but they aren't that good; all actually considerable variants (e.g. were-creatures) are in the "Other", what is only on roll of 100 and is up to GM's choice (aka he can choose to not give any kind of robust species to you).
# In Pathfinder, 3e and 3.5e being resurrected with Reincarnation gives 1 negative level, as per being resurrected. Due to randomness of ''Reincarnate'', you need to use it multiple times to get what you want; cue dying multiple times, and loosing levels multiple times. It's simply not worth it.
# "The reincarnated character does gain any powers or abilities associated with his new form. A humanoid reincarnated into an animal body can speak the languages it formerly knew and is a magical beast.". There's no explanation for what powers and abilities mean - ergo, how many useful traits of bear you would have (other than altered Str, Dex and Con), if you got turned into bear. Cue that being up to GM.

[[TL;DR]]: If we had spell what changes creature's species without dying ''into what caster chooses'', it would be funny. Druid spell ''what properly resurrects someone'', it would be useful. But they tried to mix those ideas, and that resulted in useless pile of kludge.
