Was gonna say the reaver, but since you don't seem too happy about dying, that's most likely not your cup of tea.
To be honest, dying is not really a concern outside of the moors. Just took a burg to 85 and that one didn't die once. (Untill I took it to the moors, that ended that record pretty fast. ) So, for what it's worth, don't be too worried about dying, just pick whichever class you have the most fun with. Personally I enjoy Guardians the most of all the freep classes. Just love my dorf grd to bits! Insane survivability and simple to play makes it a fine starter class too imho.
Happy travels. o/
