Training Grounds improvement and rune issue fix

Arsinik

I propose adding in semi randomized secondary objectives in Training Grounds for runes, possibly switching/refreshing each match. This would fix the lack of runes complaints and add some freshness and change to TG.

I don't know if objectives are the way to go.  The point of Training Grounds is it is a free-for-all.

I think just adding more progression rewards (like 5K runes every 25 wins or something) would be a much simpler solution to everyone's rune problems

I do like the idea though.

A bunch of switch on training grounds would be cool... Maybe if you turn on "random objectives" you get +100 runes for a win, etc etc for other options. "pick you point level vs ease!"
