I was looking forward to unlocking summon shade on my magicka based range bar for the nightblade. I was liking the idea of summoning a shade (or 2 if you morph it that way) to go out, attack enemies, take some aggro, and decrease the enemies weapon damage by 15%. I unlocked the ability and cast it on an enemy. The enemy came to attack me and my shade followed him dishing out some attacks. I soon learned that the shade cannot hold any aggro and deals pitiful damage. This skill seems like it has a lot of potential, but falls short of anything useful.
There are alot of skills that you obtain at the end of the skill trees that just arent that useful. Snipe is great for pvp or an opener, but only if you are a stamina build. Summon Shade is a dissapointment. I didnt see any improvement using Haste (bugged?). Most of the time i find myself using the first 2 skills in a tree, and ignoring alot of the later skills.
