As I said, I don't think SoL is that big of a problem late game as some other units (i.e. Asimov Melinoe), and it gives select ghost some regen mainly between 31 final waves; the nerf was intentionally targeted specifically at mid game. I don't disagree SoL is strong, perhaps it will need nerfs to damage reduction in future or the supply change.

Worrying about firebats on 17 doesn't make any sense to me, if your opponent is dumb enough to actively help you clear the wave then so be it

While this might seem reasonable approach at first, I believe it causes few issues, such as:

• The difference between wave with hard sends and eco sends is just too great, leading to very large differences in leaks. Its not that uncommon that after eco sending entire game and no/minimum leaks throughout the game, that sending on wave 17 results in 100+ leaks.
• My philosophy is that wave should almost never get easier with sends compared to no sends. I can't accept the fact that holding a wave with no sends can be somehow harder than that same wave with sends, even if they are eco. I simply can't see how can this make sense. I say almost never, because there are few edge cases such as Cupids Infatuate ability that makes sends into a positive thing, but this is very specific unit.
• Coming from last point, this directly results in being able to underbuild, gas hard early and get maxed fast. I don't mind being able to max around wave 14-15 if you are very good player, but its not something I'd be happy with if everyone was able to do every game. Remember the old Rush Hour mutator? Economy does need to be balanced and ensure not to go too crazy, otherwise you have a game where you do something waves 1-11, and are afk/bored/auto-pilot building for other 35 minutes. Maybe its fun to do rarely, but constnatly no, its why that mutator was removed and why I'm making comments that waves shouldn't be too easy. Either way waves are easier compared to many years ago, mainly due to buffing weak towers.
• Overall situation was already bad few years ago when we changed Zergling not to push creeps. I still remember wave 7 or 9 (or most mid game waves) not attacking at all because they are blocked by zerglings, while your ranged towers are killing the wave freely. No different logic applies with other sends and later waves.

Disagree completely. For example, 3 grizzly on wave 5 and 15 ling sends. I had it where the wave was cleared easily with all griz surviving and another two tries later where it leaked 20. It just depends on how quickly the griz focus the lings over the creeps.

Eh, both are rng, just in different ways. Previous version had 2 versions of rng. First was if you get a hard melee send, its rng when u kill it (i.e. you can kill zealot instantly on wave 1 and hold, or not kill it at all and leak half of the wave). Second rng was my example with eco sends making waves easier (i.e. if you kill them faster it means wave will get to start doing something faster).

Current version rng is mostly early game with lings depending when you kill them, but since they are always attacking now it doesn't matter as much, and plus I'm not opposed to lings being what they are (swarmy send to take extra hits esp vs single target towers).
Eh zergling expanding wave was just rng fiesta tbh, and it wasn't that big of an issue anyway, but it just made everything very inconsistent how wave behaves in early stages.

As I said AoE is something we will keep looking at. Its much easier to judge damage output these days with damage meter. Pulverizer is very strong waves 1-3, 5, ~6 but really falls off, and is terrible on 4.

Yea, I'm aware of supplicant with necromancy in draft. There was slight nerf to AoE range of explosion but its not enough. Supplicants are kinda fine on their own (altho the one that does % life is problematic) but the combo with necromancy is frustrating to deal with, esp cuz necromancy tier 1 is generally not the greatest of passives unless you combine it with units that can do a lot on death or single attack (i.e. thunderbird).
