I was playing on the test server this morning. I went to kuftal to try out falcorr and raphie vs some T~VT tigers and worms down there.
I was able to chain kill up to 5 solo w/ very little difficulty. Granted, I was willing to spend a theta biscuit every 3 or 4 fights though... Actually I had to use them more often w/ raphie. Frankly, killing faster w/ falcorr is a better tank. Raphie certainly takes less damage, and if you pop hardened shell, he takes ALOT less damage. but the fights take noticeably longer as well.
FYI, I was able to do 600 damage hit vs VT w/ falcorr using boost. I also did 1100 w/ falcorr using boost on VT tiger when he did a crit hit. I think 1100 from pet ready move on a vt mob is not bad at all outside abyssea.
I was also able to land 2k ruinator (5/5 merits) on the same VT mobs outside abyssea. I was using ferine body, hands, and feet, monster +2 head and legs. I'm sure most here can make a better set for it on live server.
I couldnt' get the 1100 aqua breaths... or anything close... it got resisted too much and only did like 100 damage (I used reward to cap hp right before using it) It was easier to keep hate on falcorr than raphie.
