@Riot - A few questions for the next class rework?

So far we have had 3 class reworks and all 3 of them introduced new playstyles and items and expanded upon old ones. now you guys are just a ways from your 4th rework and I'm just a tad curious on a few things and what to get your thoughts on the matter.

With half the year gone, your next rework is coming in close. We already know the three potential candidates are Assassins, Divers and Vanguards and given the amount of time needed to change around a handful of champs, tweak a few others and introduce new things without rushing I'm sure you guys have decided if not have a preference for which ones you want to do. Personally , I'm hoping you do Divers so you can give shyvana something cool but that's my favoritism showing.

• Have you guys decided on which class you're reworking or have a choice that seems likely the candidate or are you guys still completely uncertain.

• With which ever class you chose, are you worried about any new items causing game health issues for sister classes? Ex. I imagine for divers you would make an item to facilitate the jump into the fray and cause a huge ruckus inside enemy lines as a massive damage threat but what if juggernauts found a way to use this item to immediately off a carry as the tankiest AND highest damage sister class to Divers. Is that a concern you guys have?

• do you guys plan on making a lot of new items or only a hand full. There is a decent amount of items I'm the game now more so than others depending on your class but I'd definitely not object to more splong as they don't end up out of place on 98% of champions ala current rageblade and wits end

I probably have more questions and others do too but that is all I can think of at this moment, I appreciate you (or anyone's) time to read and discuss the topic of the next class rework
