There's nothing that annoys me more in a tank game than...

[jonjon]

1 or more team mates doing a TINKER start.
For the following reasons:
- Greedly like punks that want to claim mid for themselves for farming purposes.
- Rarely can they push mid.
- They die too often.
- Once towers are down they're useless.
- They end up settling for a crappy tank right after their opponent changes to heavy tank or air tank.
- When they lose, they claim they were only mucking around.

Another thing that just annoys me is the fact Infernal Tank is heaps stronger for only 2k more than Frost Tank.
First it's freeze chamber stun is nerfed by giving it 2 seconds regardless of level. Second it's ultimate is further nerfed through it's ability to stop when you move or get stunned.
Infernal tank can still move around with ultimate, hits as much units that are in range and the stun is literally a teleport.
The difference between goblin tank and sky tank is only 1.5k and they're almost quite equal. Frost should either get stronger or Infernal get weaker. Or Infernal get more expensive.

however, it can be hilarious when teammates buy or upgrade small explosives for you, continuing until you have 3-5 huge explosives and a massive range on your teleport, of course making sure that you don't get too much explosive power when not needed (no need to let them get more gold from your death than necessary)
making sure to bomb them only when they are in groups, like when 4 retreat into control point range and are suddenly all dead.
apart from that tinker should make a few factories for extra cash and buy laser towers on ruins along with his own towers on one or two key points.
excellent unit, not too hard to do even if teammates don't help.

Tinkers can absolutely help to push mid, the other players have a battle in the centre and the enemy ends up retreating at some point for health, boom, remaining friendlies take the control point

In fact difference is 5k, not 2k.
I really dont see any Frost Robot in game for a looooong time. It needs a change.

Before a couple of versions infernal cost 15k

But it is true, that because of the update limitation the frost robot is a too little step from Sky tank or even demon, to waste half of you tank cost money.
