QoL buff ideas for Ryze and Tristana
**Ryze: ** Ultimate now grants 5 stacks of Arcane Mastery. The biggest feel-bad of new Ryze is that you won't have arcane mastery stacked when you need it, and teams can just wait out your stacks if you're going to teamfight.
Tristana: Move Explosive Shot's active onto Rapid Fire (keep the attack speed steroid active as well), change Explosive Shot's active to a toggle of Explosive Shot's passive. Players have wanted control over Tristana's passive for awhile now (so you can actually freeze lane), and Riot's already done quite a lot to tie Q & E together (E range scales with auto range, E stacking, Q/E cooldown reduction mechanics, Q also costs no mana so this isn't a mana cost buff).
