What's the point of even having a perk cost for it, if you can guarantee that you will not lose those perks 
I will never understand GVers I swear
perks make it rare, lots of perks make it almost never seen, this is good, no need to have everyone in a T2 but,,, if your at the base, defending it as a last ditch effort, the T2 is a great GV for that!
you don't see ME262s hiding on concrete, they have bases far away to land at so no need, you also don't see people upping them from a capped base to make a last ditch effort to defend either, the ability to use and land a tank or a plane needs to be at least equally balanced yet the two are very different in there use and in there ability to escape, a T2 has no escape other than to tower, on concrete before capture, or drive 5 k away from all enemies,( which it has no way of knowing if it is clear), planes can dog it, even a jeep can dog it till you give up or get bombed. limiting its ability to tower out will kill it all together for the most part since the cost is so high,, if it were cheaper, it might be different but then it might also mess up the balance between it and other GV's
the perk cost is simple, it costs a lot, so you don't see it out in the open much, since it outclasses all other tanks by a great margin, this is good!! but it costs so much that a player doesn't want to venture out very far with it for far of loosing may perks! still there is no guarantee you wont lose one, a sneaky M-18 will kill it in an instance givin the chance, concrete or not!!
