Not too sure about everyone else, but the game feels EXTREMELY ANNOYING and significantly less enjoyable with ABB and ABC+ in beta strike (6 man squad, max at 8 with GTS). I keep feeling that I don't have the tools, or everyone is underperforming massively. Not too sure of the core reasons behind it, but I get bored and tired after every mission (While previously i ran double enemies with 8 man squads and I didnt get this feeling)

Not too sure if you can or will fix this. I doubt you will care enough to try, since I definitely wouldnt myself. But perhaps it may give you some insight, so I'll list the most annoying things I felt with this mod.

I almost never use grenadiers in Beta Strike, and ABB makes me want to use him less because I cant reposition to get flanks. (And suppression might as well not be there at all. Enemies either run it and not die or they simply shoot). Increasing the enviormental destruction is an interesting idea. Never seen it do anything useful though. (Also while splitting the two components of the grenades is a good idea in alpha strike, it makes the experience terrible for beta strike)

Another thing is that I can usually rely on my specialist's Medical Protocol after the 2nd mission. With ABB I did 4 missions, and only got it on my 4th specialist. Which is extremely annoying. Some skills are basically essential in Beta Strike, and not rolling them means the units would be ditched entirely. (A Specialist without field medic and medical protocol is the most useless thing in beta strike ever, after grenadiers). Well, if I can see what the specialist may get in the future, I may choose to run him in another build. Problem is that without those skills I see no reason to bring him into any mission, and hence rank him up.

I saw a reply to another player's concerns in the comments, talking about planning around the unit you get. It would be ok if you can plan around it. Problem is that Beta Strike doesn't work that well with that concept. Not rolling medical protocol does not force you to plan around that unit. It forces you to discard him instantly and try to reroll another specialist until you get one because you literally cant play after month 3 without a specialist in each mission. Heck, I had missions where I had to use 2 of them and everyone barely survived.

Ranger with single reload is a oroblem in beta strike too, simply because you rarely get time in-between pods to spam the single reload. It is also very annoying that when you get those moments, you have to spend a few turns while your ranger slowly fills up his ammo. Does not work well when the objective is ticking, or when crates are being snatched, or basically in 75% of the missions in the game where he has to get carried instead of being the carry after 4-7 turns. Admittedly he isn't underperforming that badly, but it gets extremely annoying that you have to reload every turn, and that drags out the battle because he cant move unless if you roll sprinter, forcing him to take bad or terrible shots, or double reload and leave that ♥♥♥♥♥♥♥ stun lancer alive.

Sniper sharpshooters are serverly underperforming in Beta Strike. They're the same in ABB. As in they're still underperforming, unfortunately. In fact, now that I think of it, I dont really care for Sharpshooters that much, because regardless of what they roll they'll still be underperforming. The range tables of sniper rifles were terrible and is still terrible, and squadsight penalties make them horrible units. And pistols do too little damage until you get fanfire. Then they become below average. (haha below average even with fanfire and both breakthroughs. Yeah they're bad).

I guess the problem mainly is beta strike itself, and this mod just makes beta strike even more unbearable, even for players who normally play that mode. I have no idea how to address this problem, since you will, and definitely should, priortize the regular mode more.
