-1 on Swamp Gothic: I don't quite like it; it really rubs me the wrong way, looks very much like more of a substitution with a very short list of changes that do not always make sense (uN > ỹ?) and that are not possible at the point in time when they take place ("{o a} {ō ā} > o a" followed by "a ā > o a" later on, to name an example), absolutely no vowel reduction and in general very few changes at all despite root-initial stress even up until the late 19th/early 20th century... I don't know, seems very much suboptimal.

-2 on Karahien: the tables are abhorrent, the sound changes are absurd, nonsense syntax. 2/10 wouldn't review again.
