Are Iksar a viable warrior?

[Elements]

Obviously iksar wars can't use some of the best in slot items most notably Cobalt. The next best alternative for them appears to be the Legionnaire Scale set from plane of hate. The Legionaire Scale set gives 148 AC compared to 220 from Cobalt. Does the Iksar AC boost make up for this discrepancy? How much bonus AC do iksar get at 60? and finally is the velious warrior gear iksar usable?


Thanks
