I dont use riposte as watchman. Just doesnt seem worth it, yes there's no global cd but its 3 for basically a slash(or strike? whatever your focus spender is) when I have other abilites that need my focus. You shouldnt have that much extra focus you need riposte to dump it, I mean I hardly even use the focus spender(slash/strike whatever its called) maybe once or twice as a filler till cd come up or i've spent some focus or need cauterize to come back b/c merc slash failed(at 66% >_<)
