None of the other game modes has had an impact as big as URF on the servers
BOTH URFs might I add did this to the servers.
This should tell you something Riot..Get rid of dominion or ARAM or TT and implement URF for casual players or at least make it a custom only game mode.
In fact i've never seen anything Riot's released have an impact THIS huge on the servers. Not to mention it's had this impact TWICE.
No, i'm not counting the horrible time during late season 3 where your servers constantly shut down day after day, with no compensation btw thx for that
