Epic quest line. Done that. It may be true for the Angmar / Moria line, I can't really say. But for the current lvl75 Isengard one? You gotta be kidding me.
6 piece set in Galtrev with every single piece offering +122 vitality compared to Epic quest line? Maybe I managed to pick complete chicken manure on my quests, but I'm coming up with about +50 vit on average per piece and no set bonus.
Yes, you can get 4 off those pieces with marks and medallions and yes, you can solo that.
But really.... have you ever checked how many you would need for that?
Once again, I may be wrong but a quick and dirty check revealed the following for me: 3520 medallions needed for 4 pieces. 1 medallion = 50 marks. 1 lvl75 skirmish = about 100 marks in 1/2 hour.
Total time needed to get those 4 pieces: about 880 hours doing nothing but skirmishes. Over. and. over. again.
How long one has to raid on average to get the complete set? How that can be considered casual-friendly or boosting solo-players, is simply beyond me, sry.
Some crafted jewelry is the best in game. Yes. Well, why should that be otherwise? There's already only a handful of crafting recipes that are actually worth it - for ALL crafting professions. You want to throw crafting completely overboard in favor for raiding or what?
Unbound raid rewards. Yes. I don't really see the harm here. Putting into consideration that the top item, a worn symbol of the elder king which you need for a lvl 75 first age weapon, is sold for 900+ gold, I once again can't see that as having a huge impact on the raider / soloer scale.
First age items dropping in landscape - I'd like to quote a fellow GOGer, you may know him:
f they are stat tome rates... they don't really drop in game for 99.9% of the player base.
The following are lvl75 unleveled mainweapons of the same typ (spear) for my Warden:
A legendary drop: 83.6 DPS
A crafted second age: 99.6 DPS
A crafted first age: 128.1 DPS
...... .... to put it bluntly, if the gap to the raid-only first age isn't big enough for you and you'd consider a second age (which you get exactly once from a quest) as "to good for soloers", I'll have to see you among the elitist "yo want loot? go raid!" folks. The Everquest times where you had to group to down a greenish mob, are gone. And thank god for that!
