You could give Paladin (Oathkeeper+Inquisitor) a try. This beginner build guide [1.1.8.1] Fire Shield Throw Paladin from scratch - build journal and guide by @Ulvar1 is well made.
For end game, you could stick to shield throw style, go for an aura build or (here’s the self advertising) go for a tanky aether gun+shield route [1.1.9.0] Aether Rutnick Blaster Paladin - Ravager, Mogdrogen, SR 80, Crucible 170 or a very tanky melee shield build [1.1.8.1-1.1.9.1] Siegebreaker Paladin: All Celestials, SR 95, Crucible 170ex (vid).
