Okay, I like the idea, but this will fuel the current tanking even more.
Tanking in the gameroom environment is already a big issue, that effects nearly every battle I currently play.

People want silver to improve their gear, but can't get it due to tanking.

Also the matchmaking needs to be addressed. As soon as one hits Diamond league, you will be facing champions and champion squads. Again less chance in gaining Ag.

how about the WSP that you paid for, but were still in production?

WTF??? Why increase the cost and time of the Lancelot to such impossible levels? Why???? It is already hard to upgrade it past lvl9.. Will be impossible now. 20M just to get it to lvl10 and then almost a week to wait???
