You can actually use one honor party to get a player to 50/50/50 or higher. The level 30 honor thing is just the limit that restricts you from MAKING the party, after that as long as you don't leave the party or crash you can plvl for 3 hours with no issue.
Yep. And there are ways around that too. As you can see in the video.
Before you say you need to reset party to reset instance, all you have to do is wait 5 minutes everyone waiting outside the instance, after 5 mins it auto resets, and you can go again. Sure its slightly slower but there is no issues with class level that way.
True. If doing HOS, like I do, entering HOS easy and normal alternatively avoids the delay. Might work in other instances too, if you can solo normal or hard mobs.
Any class can kite bugs in tosh, but its only scouts and mages that can effectively kill the bugs, though only just on scout. Anything with range hits can farm, true, but unless you do enough damage you will very quickly get so many small bugs that the lag is terrible... Personally with my comp I can just handle kiting 4 bugs, but if I stuff up at all and don't kill off the previous wave my fps drops to anywhere from 1-8 and I get owned >.>
I'd be curious what the XP per kill is in different instances. Tosh is good, but it is not simple process to do, as you mention, and risky. People, depending on their power levels, can choose others. Anyone has numbers, before the 30% party buff and 100% XP fruit? Lemme start:
1) HOS/HOS-e = 1980
2) KS = ??
3) Origin = ??
4) DOD = ??
5) RTE = ??
6) GCE = ??
7) SCE = ??

Tosh-E = 821 (about 9100 for hard mode bugs)
