what it's the best melee solo class??

Iksar monk probably easiest. Save up like 1kp and you can get decent weapons and armor (sans haste) with wu sticks or staff, azure sleeves, tar goo strands, 4/45 hp rings...monk is just so easy to gear. With mend you'll have lower down time, plus fd at 17 you can get out sticky situations, and you can make some macros to bind wound in combat. SKs don't get any spells until 9,fd until 30. Weapons that are close to monk ratios on sk cost 10x as much.

Obviously if you have more plat to spend you can twink a monk more...made 1-45 solo on my monk in roughly 45 hours played with cof and fungi, and this was when they had a 20% penalty

Also I still solo a lot for xp on my 59 monk, decently geared but no raid gear (unless you consider hot armor raid gear.) Still make 4-5% an hour in 59 which I don't think is bad for 59, quadruple hell.
