I totally agree that this so called 'yo-yo' buff and nerfs is annoying but the problem doesn't stem from NG lovers, who can't live with NG being butchered but rather from NG haters who can't nerf NG correctly and in a fair way. I like playing NG and although I don't consider myself an NG lover, I am by no means an NG hater either. For the record: I have voted to nerf NG - dame to 6 provisions and some nerfs to imperial formation but I don't remember now what exactly. The problem here is as follows: nauzicaa seargant gives 10 points for 6 provisions (conditionally on your opponent winning a round), which is much lower than consistent values of onagers, fleders, ancient foglets, etc. and at 9 power there's no comparison to e.g. griffins (9 for 5 with fruits of Ysgith), this simply doesn't make sense - griffins can be played even in round 1 and summoned in the final round with incubus, mammuna, can be consumed with ghouls, etc.
Personally, I'm fine with nerfing power of nauzicaa seargants but after that their provision cost should be lowered to make it fair. As far as slave drivers are concerned: I'm not fine with them at 6 provisions - would need to increase their power to make them at least close to other 6 provision units (do NOT compare with reaver scouts, please, that's another story). Unfortunately, people on the Internet are much too divided and unorganised to make such coordinated changes, which results in 'yo-yo' changes. All we can hope for is that either russian streamers coordinate it or maybe other group (Reddit or whatever else) finally manage to organise a normal voting.
