How about more Ascension classes/trees?

Marauder: "Shaman" (Summoner Ascendancy.) Devoted to the ancestors, empowers them with his own flesh. Nodes grant minions the bonuses from active Ancestral totems, then a portion of the damage of the player's own equipped weapon, enabling a hybrid summoner/melee Marauder playstyle. Additional nodes grant the Shaman bonuses when his minions kill and grant the Shaman's minions bonuses when he kills (possibly granting bonuses to both when an Ancestral totem kills), or possibly allows the Shaman to trigger summon skills on melee hit.

Distinct from Necromancer in that the Shaman is intended to wade into battle with a giant axe and fight alongside his minions; Shaman is distinctly inferior to Necromancer as a traditional summoner, but would be fantastic with an SRS/Ancestral Totem/Disfavor-type playstyle or set-up.

Duelist: "Buccaneer" (actual good name pending) (Critical Ascendancy.) Focus is on turning critical hits into momentum, as opposed to enhancing critical strike damage as per Assassin and Inquisitor. Nodes grant increased attack speed/base (non-crit) attack damage per Recent critical hit.
Also offers 'Break the Guard' node, similar to Elemental Overload save for physical rather than elemental damage, to enable a moderate crit playstyle. 2 points can buy ability to inflict stacking 'Off-Balance' debuff on enemies per critical hit applied in last 4s/8s/whatever-is-balanced, reducing enemy movement speed and accuracy, with second node offering increased evasion/dodge chance against off-Balance enemies, or possibly reducing enemy damage resistance when Off-Balance.

Intent is for crits to be defensive and utility in nature rather than pure offense a'la Assassin and Inquisitor. 'Physical Overload'-style node, and support nodes behind Off-Balance, allow moderate crit investment to still pay out, while high attack speed, crit-heavy builds can build stacking buffs/debuffs to swing longer battles or high clearspeed in their favor.
