I honestly think the Air Strike needs a buff, it's straight up worse than the Rocket Launcher, I'm not even understanding the -15% blast radius part of it either. Seemed like they just added a random negative attribute. I mean it only gets useful after like 6+ kills and only if you use almost every rocket you have. From the air, unless you're in the enemy's face which defeats the purpose of an aerial advantage, make you do a ton of 30ish damage (unless you nail every hit directly which it still only does like 50s) which requires a lot of prediction and luck to even make most of them hit.
All in all it's fun to use, and almost seems like it's perfect but it's damage output is a tad too low to be useful, I think even removing the negative radius attribute would make it perfect. It also shouldn't get random crits IMO.
