Mainly because of plot armour, one Ork in melee against a marine has a fair chance of it, they are as strong and certainly as tough as a power armoured marine there. Of course ork shooting, eh, yeah I will agree they shouldn't be nearly as good, allot less damage allot more suppression to allow them to try to close. Of course one squad of marines suddenly becomes much more dangerous as they are able to use teamwork as a force multiplyer much better than orks.
I expect we'll get much larger maps when the vehicle warfare expansion drops, whenever thats supposed to be.
They should of balanced everything before the games release, but that obviously didn't happen. *so salty.*
