First... Strikes are waaaay worse than vomit, and it really should be the first thing addressed, if anything.
You are right though, vomit is pretty powerful. At higher teirs, its very strong.
The catch is, for casual players vomit is no stronger than missles or dakka. For high teir 1 solo quick plays Vomit is stronger than everything. For organized competitive groups (cw or comp queue) vomit is usually weaker than brawl (map dependent ofc), and sometimes erppc's or erll are still the best choice.
The question we all need to answer is what kind of player and game mode should the game be balanced around?
At the moment, it is clear that the game is balanced around casual players, as shown by the multiple AC nerfs that have happened over the past year or so.
I dont think that balancing the game around teir 1 solo queue is smart because average players wont undersand the balance changes, and its not really a "competitive" game mode, its like the arcade mode of the game. At the same time, I dont know that balancing it around casual players is wrong, most people that play this game are casual players, and that is great
The wildcard here is the spectator mode in solaris, because it will give every player an insight into how top players play. I'm hoping this will also eventually feature comp queue games. Hopefully this time next year, 8v8 comp queue is starting to become the target for game balance. It would by far be the coolest thing the game could be balanced around, and I hope a strong competitive scene would bring in more players from outside the community. But, you cant balance the game around high level play if the average player cant understand it.
I think possibly one option to hit lasers pretty good in QP in the meantime, without actually playing with weapon balance is just to add another hot dakka friendly map to the rotation. I've actually been thinking about this for a while I think I'm going to make a thread about it after this, but I have always loved Vitric forge, if we could get a map with new topography that used all the old assets from Vitric in a QP map I would be super happy.
