I'll say what I said in the other thread about the same thing in the past 2 days. This will just give rise to spamming WAR/SAM and SAM/NIN (or /DNC or /RNG) as the "it" jobs. Sekkanokki, Meditate, Store TP, and access to every skillchain in the game, these jobs will pretty much be the only jobs used to proc in such a way. As for magic bursts, that really would only change when a BLM has to nuke not the job that would be doing it.

They need to up the effectiveness of these game functions not add proc'ing to them, or add new skillchains that can only be executed if you have a specific job(s) in the party.
