I main tanks and know Courage of the Colossus is busted. We know it's getting nerfed, let's talk
Current effect of this mastery: "Gain a shield for 10+ 10 per level + 7% of your maximum health for each nearby enemy champion for 4 seconds after hitting an enemy champion with hard CC (30 second cooldown)"
New effect: "Gain a shield for 10 + 10 per level + 4% of your maximum health for each nearby enemy champion for 4 seconds after hitting an enemy champion with hard CC (45 second cooldown)"
Why increase the CD? Trading against that shield every 30 seconds is NOT easy in the early game when you're laning - making that CD 15 seconds longer allows a bigger window for the opponent to make a counterplay. Why decrease the ratio? Well, let's look at it from multiple points.
You have your tank junglers that are CC bots, pretty much will always have it off CD. tank supports that are CC bots, who can make aggressive plays every 30 seconds because of it (
).
Then this is the least threatening case, but still a point to bring up - top laners stacking health.
is probably the biggest offender here because now you're better off building
into tank rather than going more for damage with fervor (because it's not that reliable now unless you've got a tank already), which at least made him somewhat of a risk pick if he didn't do a good lane phase. Not to mention you can still run supports in top lane if you're going off-meta who proc it easily.
I'm sure some people are already going to call for nerfs on every tank or the reworked tank items / new supp items, but not the keystone so here's the logical thing to do :^)
