And the question is can someone explain how will work the tier 19 4p set bonus
"Paladin T19 Retribution 4P Bonus - The effect of Conviction can stack 2 additional times and you have a 20% chance to gain an additional application each time it triggers."
cuz Conviction is: beta.wowdb.com/spells/115675-boundless-conviction
Requires Paladin
Requires level 1
You may store an additional 2 Holy Power beyond the maximum of 3. No ability ever consumes more than 3 Holy Power.
and this is the point when the setbonus loses sense from my point of view..
