And in my desert soloing career I can clear the thirsty one, the mad dude and the three mummies with only using one or two cure mod pots and still have six minutes left on my GH, I use that to time reset.

It all depends on your solo'ing technique and your playstyle.

Some cant solo worth a ****, others love to solo and make cakewalks out of quests.

Personally, I love to solo. It doesnt matter what it costs in gold, I dont play to make gold. I play for the challenge, for the fun, for the LOOT!
When I first started this game I didnt realise other people were playing at the same time as me, ON MY SCREEN :-O so I solo'd everything...until I dunno, level five or six or something...then I started to realise that you could PARTY with these people I see talking!
Yes, it can be more fun to party than solo, but solo'ing is a great way to build up playskills imo.
Think about all the noob level 14 you've encountered and how they dont know SQUAT about the game, asking for lesser restore wand whips or no resist pots/cloaks etc. If these people had solo'd at lower levels they would have a better understanding of what it takes to survive.

Solo play made me better, thats for **** sure. Everyone should solo just to gain the knowledge of what it takes to survive.
