Its all good man, i play on Xbox and have a good regular 4 man team. We still kill Wraiths, just there are some pure cheese wraiths at the moment that make a match against them just not fun. If one of my team aren't online and we have to take a random, that's sometimes enough to spell doom against even an unskilled wraith player. That's not right. One of the guys i regularly play with, he plays monster a lot too when we arent all online, and like you he refuses to play Wraith until it is nerfed too, as he thinks its just not right.
We can see how it goes with the upcoming changes. The Kraken changes will also help against stage 1 Krakens which seem slightly OP. As for Cabot, i do agree with the changes now, i used to take damage+ perk with him for extra headshot damage but in a defend yesterday i took reload speed+ and it was ridiculous how much damage i was putting on the monster alone, even without the extra accuracy of a mouse, though i am pretty good with a controller. I can see how headshots and accurate shooting could be even deadlier with a mouse though.
Looking forward to the Val changes, recently started on my medic play and i love Val, she is brilliant.
