I repair tanks as often as I can (I always play engineer), but its a real pain in the ass when you dont get support from the aux gun (he's usually wasting his bullets on the tank opposite to me, not caring about the infantry moving up from behind).
Also, every time im standing with a tank in my facing holding the e key and watching what looks like a load bar I always gets reminded of a Hacker News post that read something like "dont make your users do shit work". The article described how google plus was doomed to fail because the first think you had to do was shit work (arranging your friends), whereas on facebook it automatically just made relevant groups for you that was good enough. And I cant help but think that having a huge green blob in my face (that eventually just leaves me, not caring if i helped it or not) and watching a load bar that I myself can only fill up by just holding e is kind of... shit work... not game play at all.
But then there's the thrill and suspense when me and a friend are holding a street with our tank and i hop out to repair while he covers me and I run around the tank and shoot an anti tank missile just to get ahead (because the other tank also gets repaired) and we end up winning that battle because I multitask so much. ![]()
