hmm i guess u did forget something.interested in armory / values. Reaching multistrike cap should just be a problem with specific gear sets on very high itemlvl. Probably mythic warforged stuff or lots of sockets.actually i have exactly the same problems. For me its actually Haste>crit>multi with crit-enchant on weap and every socket/gem = multistrike. If i change 2 enchants to haste Simcraft provides me more dps and multistrike is getting the less important secondary stat even after versatility and mastery (lol).
Weapon enchant x2 ~15% (1000 multistrike, 66 rating = 1%)
Icy veins ~ 30%
Bufffood ~ 2%
Buff 5%
~48-50% from gear depending on which bufffood you do eat. But the decline of multistrike as a value may happen before that value (I doubt that one). Thats the reason why I'm interested in your gear. Anyway, if you're able to reach that one exchanging items for higher itemlevel ones may be more rewarding than changing enchants. Higher itemlvl = more int. Int wins.
icy veins with frost mage draeoner perk (improved icy veins) is giving u 45% multistrike, not 30%
so with the VP-upgrades u are pretty fast over 100% with all possible buffs:
~41-44% MS from gear (average on heroic gear level)
~45% MS from IV
~2% MS bufffood
~5% buff
93-96% Multistrike. If ur weapon enchant procs now u are over 100%
pls tell me what the mistake
