I've been duty finding Garuda HM as a PLD tank and...how do you grab the red lined minion extra fast and never let go as OT during the first part of the loop (arena not reduced)? As I main tank garuda herself alot (others either seem to have less HP or just want to OT instead of MT), I can only watch as the rest of the party struggles with the two minions and hope they survive through it and kill them on time. Some times I see the off tank unable to keep the red lined minion in check and it lets loose on the party along with the green lined minion and they all die, then I die, then the OT die. Sometimes I see the off tank clearly prepared for it and fighting hard to get the red tank but to no avail.
I've off tanked for the fight too and I face similar problems. If the red line spawns right at the party area, I seem to have a decent chance of grabbing it early: shield lob, start combo and go to my little corner between the north circle and center circle.
If the red lined minion starts at the other side...I've tried provoking first for (0+1 enmity, yeah yeah) and then mashing shield lob it as it comes closer, get the red icon on enemy list and then proceed to watch the minion ignore me and go for the group, start comboing it hard+ spirits the red lined minion who seems to still be hellbent on cleaving the group two to three times before it finally turns to me. I thought it might be because the healer is aoe healing hard and gotten on top the minion's list (but i'm unsure since so far I have not managed to take a good look at the threat list during this and besides, like I've mentioned, I have the red aggro icon the whole time) so I started to just lob as soon as i can and start comboing and provoke if it still ignores me after the first fast blade or savage blade. It's not...always succesful but I really cant tell what needs to be done otherwise, on my/ot's part.
Also, I prefer just stone skinning up when she summons the minion and using sentinel as she casts slipstream and just take the hit during that phase. I've never tried running forward to bait the slipstream before running back to my tank spot. It seems to be way too risky on the OT behind me if I do that and doing what i do... I only take like 20% dmg of my HP max. Should I not be doing that?
