[8.53]Goblin Tank too weak?

[Morkardar]

A speed burst for the hammer would make this tank very very dangerous on its own.
A good solution in my opinion.
Those heavy scout abusers will have to change tank soon or get crushed with the mighty hammer
Goblin Riot is weak sometimes, but has its moments too.
It is very strong against huge packs of creeps on a long run.
It also can sometimes be used as finisher for running tanks... they are pretty fast.
Maybe they can be made even faster *g*
