that's only part of the problem, the other is the gap that is widening between tank aggro abilities and top tier dps, making it nearly impossible to maintain aggro without a stacked group and adding memwipes to add fuel to the fire. more proccing damage will help this situation to abilities that are wasting space in AA trees with almost no usefulness.
we already can see that the point of strikethrough was mainly to keep brawlers from taking up pitchforks and stakes, even though they weren't doing that bad in TSO.
