On Tanks and Wave Clear / Csing

gold plays too big a factor in this game and inabilty to cs is harsh/takes its tole. Issue is particularly relevant on single target spells and auto attacks heavy champions. the skill cap to cs on tanks is so much harder than on say yasuo who eats threw waves hardly ever missing a last hit.

So here are some Ideas to help tanks keep up with dps champs wave clear speeds and reliability to last hit. Feel free to add some too.

i propose a tiny buff to s New passive: (something similar to 's death mark) if minion on brink of death sunfirecape kills anything at 45 hp or less every time its aoe triggers. (I miss the old sunfire that had 40 flat magic damage because it could be relied upon for last hitting).

right now it actually makes me miss cs. I make it a point not to rely on sunfire for last hitting minion because its not reliable at all. this prevents me from effectively using it for wave clear which is whats its meant for.

tank mastery tree needs a better way to wave clear / cs disadvantage next to offensive tree. How about a mastery gives something like give +5 magic dmg single target spells autos. from level 1 through 6. could tack it onto say Oppression in addition to its current stats. or dmg to creeps that scales off armor/mr or hp.

tanks also tend to get things like magic / hybrid pen (which doesn't help vs minions) all this add up. Mages got runeglaive, imo tanks could use something too.
