You should never need to do Gribbles when PL'ing with a 115 SK. I have only done a couple of toons, but below is what I found to work best for me.
It may slow down a bit at 80 or so, but you can do The Grounds to level 85, at which point grouping with the SK will be your best bet. You can actually do The Grounds from 15 to 85 and skip the hatchery completely (I find the hatchery approach a bit slow).
For those that haven't done it before (and yes, there are other guides, but they all seem to gloss over a few details):
- Park ungrouped PL'ee in a safe spot. I prefer just outside the door to HoT as this area has no named with AoE's.
- Pop merc healer for the SK (you can't heal the SK with taps and even level 80 mobs can wear you down). Set SK as puller so merc stays put. Can maybe skip healer if using Wurmslayer, but risk riposte damage if you do.
- Equip zero damage items in primary and secondary. I use a fishing pole and a fire beetle eye or two FB eyes.
- Go out and round up some mobs. Grounds mobs have crazy aggro, so you don't need to do anything but run over them. Don't stop running - you want the mobs all behind you, and coming at you from roughly the same direction.
- When you have enough mobs (one side of the field is usually good, but start small), run back to camp but don't go all the way. Turn around and face the mobs. They will not be able to hit you and will not take DS damage. Let them bunch up as the AoE range isn't huge. Cast PBAoE hate spell (Revulsion, Contempt) once or twice to make sure you have all of the mobs attention. Do not reply on AA's like Explosion of Hatred as these hit a limited number of targets and you don't want to miss any. Take as much time as you like, it may seem hectic and something you need to do quickly, but if you are facing the mobs there is no risk of some dying from the DS before you are ready, as they shouldn't be able to touch you. Similarly there is no risk of your death even if no healing is incoming.
- Once you are sure you have the crowds undivided attention, move into camp. At this point you can turn your back on the mobs so they start taking DS damage. Note that this starts the clock - the PL'ee must get at least 1 point of damage on each mob to get EXP. Depending on the class this can sometimes take a while. So you might need a couple of pulls to know the best time to turn around so the mobs don't die prematurely. Also depends on how high a DS you have access to.
- When down to the last mob you may want to snare them - some of the mobs in the Grounds run on low health. This is just annoying, as they usually don't come back.
Tip#1) PL'ing a class with a PBAoE damage spell is pretty easy. But if you start at low level (15+) you will get a lot of resists, and casting the spell repeatedly takes too much time and risks aggro. I highly recommend picking up The Golden Pick via the quest in Blightfire and using Hitall.mac.
Tip#2) Set up two hotkeys on the SK. One to move the PL'ee to your current location and run 'hitall.mac' (or cast AoE spell), and the other to end the macro and return to camp location. Prevents needing to really bring the mobs into the camp at all, and you should never need to switch away from the SK.
Tip#3) Take your time. Face the mobs with FB eyes and you should be able to go AFK. Don't bring them into camp prematurely - deaths slow you down more than a few seconds spent ensuring the mobs are all close enough to get hit with your aggro spells.
At 85, and also with an SK and any support team, I recommend grouping with the SK and going to either the drachnids caves or yeti caves in Lceanium. Put SK on Hunter Tank and go. Can easily go to 106 there, though I usually push to 110 for the ToV armor (the PL'ee stays nekkid to this point).
