Hail of bombs imbalanced

[lyf590]

but if you are not flying you can be blocked by creeps, other tanks or the environment so you might not be able to get out of the bombed area

That's one of the reasons why a 4.5k gold air tank has 3600 hp and the 4.5k gold ground tank 4500 hp - even more than one additional hit from lvl 1 ultimate.

when i use the airship i always seem to be able to get out of the way without much damage for some reason..
but ground tank its a different story. even if it has more hp, stun+hail of bomb would do around 1/4-1/3 damage to ur tank, or even 1/2 to low hp tanks in mid game. So now u have a damaged tank with 2/3 or 1/2 hp, and u got no creeps around u cuz they were killed by the ult, the enemy would usually chase and kill u.
