Thunder Tank stun duration - heavy tank stun duration

[Gammagulp]

I know the heavy tank is really popular, but why does the heavy tank stun 0.2stun per level, which is really low at lvl3 (you are lvl 9 maybe) --> you got 0.6 sec stun.

The thunder tank, which cost 4.000 and is therefore be able to get earlier - has 1.5sec stun WITH 50 Area effect, which has a big impact if you hunt an enemy which is retreating even with creep support. - wih combination of the ultimate its quite hard to get away, partly even with a heavy tank.

Did you play with the unbugged drones from the 4.500 Gold airship against a 4.000 Thunder tank? - I played sometimes and found it annoying. - 1.5sec stun +area effect + ultimate (chain lightning) kann kill you very easy if you dont care.

I know the heavy Tank has a good ultimate with that bombs, but the thunder tank player get his tank 1.500 gold earlier and can creep better till the other gets heavy tank - so maybe has 2.000 gold more available - maybe for weapons - until the heavy of the enemy appears

I would like to see a little slower stun duration maybe 1 second, because the 50% area damage is a good bonus already.
What do the others think about ?
