Few questions about the things coming in the near future @Riot

Wanted to ask just few things:

1. By looking at Taric's rework, you actually made him more difficult to use, not complaining about this, i love more gameplay depth, just using the perspective of someone who started to play league. The number of champs being "easy to play" is decreasing lately, by reworks and by new champs (such as aurelion which is hard to master), do you have any plans to make more champs available for a less elite group of players?
2. With the removal of the Spell Vamp stat with the upcoming MYMU, i saw you considered cases like Akali and Vladimir with this change, i wanted to ask you also about Mordekaiser who actually relies on the use of spellvamp to survive in the brawls, do you have any changes for him planned?
3. The tooltip for Nunu's passive about eating jungle monsters is a bit old referencing to "Elemental" and "Undead" monster category which belong to Summoner's Rift before the rework to this map. Will you clarify this passive aspect? (This question is more about the present) Thanks.

Edit: 4) Any plans for Karthus? I feel like his ult ,with the current roster of champs, has too many counters making his ult incredibly unreliable and making his pick a huge risk of getting countered.
