With the revamp of Tenser's Transformation, arcane melee builds seem to become more viable, and in particular Sorc/Paladin/Rogue splashes might become more interesting now. There seem to be two popular splits, namely 12 Sorc/6Pal/2 Rog and 16/2/2.
The former has more melee power (DoS and Divine Righteousness), but can only afford one level 6 spell, i.e. either reconstruct or Tenser's. Scrolling Tenser's means a boost for 1 minute and 6 seconds.
The latter one makes less use of the paladin splash, but has buffs which last longer. Are there more notable differences between these two builds?
