Of course that always been the case somehow, but is even more true now.
In most of the game I play now (about 1 year, but that has been more emphasized since 0.92 (and started around ba 6.82 but that is not the point anyway)) it just about spamming a few unit: banta, reaper, scout, ...
Not saying those are complete unba, it is more than that.
Janus and riot used to have much more impulse vs t1 and even t2 unit, that was somehow the only way to fight with mobility against T2 (A consequence of that is that the t2 rush has become more of a necessity but whatever.)
And paradoxically, the new pathing make units almost merge together which make most of your attack you do with a large number (either T1 or T2) far less effective because unit just stay close together and AoE effect are emphasized. Even super micro every one of them (which is a pain anyway) does not always work. I believe some player stop play 1v1 because of that pathing behavior: Johan ? (Anyway, not blaming pathing, trying to point fact for now.)
The 1st result of that is: games are much more focus on ecoing since defending has become easier against large amount of unit for the reason stated above.
The second consequence is: the more robust way to kill you opponent are units that have a lot of HP and are fast..(reaper and banta) and it does ruin the awesome game ba used to be with a lot of units needed to win.
The point is BA has become boring to me (mostly ffa) :
- I know what I need to do to win, spam a couple of unit, rest does not belong to me, my allies, or other opponents in ffa will decide the game. Skills has been leveled, a lot, by that "balance/engine" tweak. Still those guaranteed-to-win guidelines make the game boring.
- So maybe I just get bored overall, but a lot of players I talked to kind agree with me (and ofc some pips just enjoy contradict me :D), or just dont care... Unfortunately, here, almost no players replies (except johan) , or those are just playing large team games with always the same mechanics: That the reason I made this post: so a player who can win (no bawing here :D) give his point of view.
I do not want to piss off any BA devs (or maintainer) whoever there are or make them feel they do shit or not enough, but I just want to warn them BA lost a lot of what use to make it awesome to me:
- fight with less eco if you multi task a lot and use a large variety of unit
- have a lot of unit combination possibilities to win.
It is obvious to me, it is not the case anymore.
And if some of the engine changes might have been the reason, I believe there are some ways to fix it.
So my question is: Does the BA dev want to go back in that direction ? In that case I will be glad to suggest some balance changes if I am ask to. In the other case, well , I will just miss the old BA...

But at least, I know where to stand, what to hope, and in the case the direction is not the one I hope it is going, I wont waste time posting anymore, you wont waste time reading me: win-win :p
Looking forward to your answer, and please erase flaming and personal-oriented post. Thanks.
