BIG PRESEASON FOLLOWUP PATCH. If anyone remembers last year's followup preseason patch (it's only been a year but check out the progress we've made!), we were very conservative with our changes.
Not this time.
While it's true we've introduced a lot more change in the 2015 preseason than 2014, it's also worth highlighting how many more 'design levers' we have to tune with. That's a fancy way of saying we have the right dials in the game to crank up or down when something appears too strong or too weak - all without having to fully reconstruct the kitchen. We're mixing metaphors, but you get the point.
Anyway, the big narrative before we ring in the holiday break and the new year is systems cleanup and last-minute gifts for League's many orphaned champions. Talking about the system changes: while we're happy with how the preseason has progressed, we saw a number of opportunities to address the more egregious problems (snowballing, early to mid game gold flow, jungle balance, Warwick). We know everyone's still getting adjusted to the new preseason, so we'll be watching closely over the next while to see what new Warwicks come bubbling to the surface.
