Never understood XP for lack of performance

DeviouslyCursed:  This is wrong. You have no idea if they contributed or not. Back when I had XVM, map was cliff. I had my Cent I or Cent 7/1, can't remember which. We had a purple in a T62A.  Start of map we went to take and hold the West part of Center, that overlooks valley, the most important spot to hold. He pulled out, took a shot, and got tracked, he repaired and started to back up and got tracked again. There were two arty on the map and I knew instantly what was about to happen. I slid my Cent right up beside his, pushing him a little bit more broadside but completely covered by my Cent, and SMACK - SMACK! Two arty shells obliterated my tank. I died with 0 damage and basically "no contribution," but the T62A didn't take any damage from the arties. The T62A went on to get over 5K dmg and carried a close game. Technically I did nothing from a end game stats point of view. But make no mistake: I won that game for us, just as much as the T62A did. Guy messaged me after the game and thanking me, acknowledging I won the map because of that move despite being either bottom or next to last in xp with 0 dmg. Do the bottom people do things like that a lot? No. But it doesn't matter, a win is a win. DISCLAIMER: This was on my main, Eagle5, before someone points out I don't have those tanks on this account. And back then I was blue, so sacrificing myself to attempt to save a purple was risky. But he was also higher tier. It's crazy all that went through my mind in about .5 seconds when I was deciding whether to help or not.
