Throughout the years, I've generally admired Riot for their business model and attitudes towards running their company.
LoL is legitimately f2p, and buying skins/etc. gives you no advantage in the game. As a small company, they worked hard to make their game rich, enjoyable, and legitimate. They did very well and deserve their success.
As a large company (with a parent), they are trying to do something unprecedented, and I can admire them for that as well. They've come a long way since that live broadcast of S2 worlds, and are clearly working hard to blaze trails for League as the first "mainstream" e-sport.
Personally, I want them to succeed. League has become such a rich community, going so far beyond the game itself. I remember hearing the first League-related music and thinking it must have been a joke, but no. We have League art in every conceivable form - from sketches to elaborate sculptures and life-sized equipment, to say nothing of all the cosplay/costumes people have come up with.
It would be a shame to see everything that's been building up to this over the last 5+ years get ruined by a few bad decisions. DQ in particular is not something that can be "fixed" or "tweaked". It's noncompetitive by definition, and you can't change that fact. I have nothing against a "ladder" that lets any sized group join, but to replace the competitive ladders with this farce is an incredibly bad move.
