BG: 25. Raidable.
NoM: 35

Kalins: 50. More geared than Clops.
IDK 50: ...50. Pretty well geared.
TT: 50. Almost HOTO geared.

IDK 35 is NOT a lvl 35 instance...i have seen lvl 60+'s die due to the weird mechanics of the instance...and it is crazy hard for a lvl 35...i rate this one as harder than MA...i can solo 99% of MA(which, btw, is about 3-4 lvls higher than NoM), and i can't get past 2nd boss in IDK 35
clops is a little harder than KS if you do not know the mechanics, but gear-wise, i agree, it is easier...and it drops the best lvl 50 gear sets...besides those snow ones in ystra
