Lol I love the pay to win crap. Pay to win means there is no other option to obtain something other than to pay. If Runes had a RP and IP purchase then its merely Pay for convienence which there is nothing against at all. People that have money can get them faster, big deal? If IP still remained which it would, it would be no different than now. Also runes don't affect much. The average AD rune page gives like 15 more AD, some armor and some mr or AS. that isn't going to make or break anything to the point where if you play poorly you still win.
People need to actually learn what pay to win means before using it. Nowadays people spout that around to the point it lost its real meaning and only to say something is wrong since they don't like it.
I'll give an example of what real pay to win is. An old game I played, Mabinogi had different difficulty dungeons. Problem was you could only reach the levels beyond normal with a thing called rebirthing. you kept your total levels but your current levels got reset so you can get a higher total and therefor tougher, that costed actual money to do. So you wanted to play endgame stuff? You needed total level 500-1k to do it, which required 10+ rebirths, and those things werent cheap either, was like $13 per one. That my friend is actual pay to win.
