I really don't see how you can call Orks underpowered right now. They can tech up very fast and can start pumping out dreads quickly and cheaply (after getting to tier 2 I knocked out 5 dreads back to back and rushed their base). Not to mention having (IMO) one of the best tier 3 vehicles in game right now. That looted tank is very good... I think it is borderline OP right now because it costs slightly less than a pred, only costs 15 pop compared to the pred (18) and for a race that accumulates req so fast they are very easy to get hold of compared to SM who get crippled economically late game. They have excellent accuracy, amazing range, good manouverability so can kite dreads with ease and do good damage against all targets including heroes.
I mean whats not to love about the ork looted tank... hell I play SM often and I wish I could buy the damned things.
The only thing I would say against the Orks is that the kommando hero is a bit dull. Who wants to buy an ability that blows your self up or one that drops a grenade when you are running away like a pussy? Not very exciting to be honest. The remote detonated bomb looks pretty cool I guess but I can't be bothered when I have stickbombs. I normally always get the special shoota, extra equipment and stick bombs and then lose interest.
He's also got an annoying pathing issue that means he often has to go the long way around while ordinary orks can just go through the gap.
Why can't the kommando get that kick ass belt fed machine gun that the mek boy starts out with. It should have an ability to suppress infantry at will. Complete with stickbombs and an armour choice that increases his energy and gives a sprint ability then he could make a pretty good lone fighter.
Or he could go more of a stealth/raider path perhaps with a sniper rifle (that would be frickin awesome!), an armour that makes stealth drain no energy and dramatically increases his capping/decapping speed and then he could have mines/traps (mekboy upgrade atm!) so he can cause chaos behind enemy lines.
I think the Mekboy is by far the best commander for Orks at the moment. That starting gun is great and only gets better with upgrades and has the forcefield and teleporter. Then for abilities he has the repair and kult of speed, which are brilliant for that ork dread rush. Not to mention having a repair ability himself so if you have enough dreads attacking the base you can take one of them out and do repairs while the others keep the enemy busy, rinse repeat till they're dead.
