Calling the math people!
As we all know, green gems gives a higher critical rate bonus to our offhand than to the main hand. A lv 6 green gem gives 42 critical rate and we usually wear it on a Karacha Dagger, so 42+11 critical rate and 11 evasion + damage/critical rate awakening if you're luck.
Only recently I realized that the new shield Didel Tower Shield (ok, this one is not so new) has two, TWO slots for gems.
Two lv 6 green gems would give us 84 critical rate. In a two lv 7 gems scenario: Karacha = 68 +up to 14 from a possible awakening vs 114 from the two slots shield.
There's also the New Lion Dagger: 12 dex, 8 evasion and 321 fire damage so we might consider this dagger too.
But since we're fencers so... the question is:
Rapier mastery's +15% damage and some evasion vs extra critical rate and super strong block on demand (for pelts, Epee garde kills the shield's defense, but block and extra physical def on C guard still works).
How much DPS I'll loss when wearing a shield?
We need to consider that Epee Garde = not crit, no damage and the new content is very hard to solo. Investing on a shield like this is really worth? I can switch gear without problem to do a better burst (like when preparation is up), but I'd like to hear more opinions and maybe see some numbers before considering this investment...
