For a start he needs ease of use buffs for his artillery strike, the targeting system is way too awkward, if you point at an object for example- it should start its targeting zone right there. Because currently it is impossible to get an artillery strike on a bridge, or a vehicle or what not. And the other half of the time it seems to spack out and glitch around the targeting zone, instead of firing, or just tell me it can’t fire when i’m 1500% sure it can, throw in an extra 30% radius and you have the definitive changes I damn sure want to happen.
Apart from that, frankly, I wouldn’t mind his E being changed into something else, to stand him apart from the others, maybe a tear gas grenade or some shit, lasts 10 seconds, deals small damage over time and distorts the vision of those that enter, it’s only fair that an artillery based Merc has something to clear buildings out so he can use his artillery strike.
These changes make him a valid pick across all maps, and make him more desirable in more situations.
