Something i was thinking about, and wanted to share it with other people.

Two out of the 4 classes have an option to summon a partner (or partners). Sorcerers are the most noticeable ones, with individual 3 summons.
Nightblade is the second class which can summon allies in combat, with their shade skill.

DK and Templar are the only ones who always fight alone.
Though some might think/ say that summons aren't needed/ just a waste of skill slots, they have some potential when it comes to combat.
Supporting the fighter in combat or taking the heat of the fighter altogether, they can be pretty useful.

For DK's i would suggest using the "Inferno" skill.
Let the Inferno skill summon a Flame Atronach, which will use fireballs against the enemies of the DK.
Since a Summon has a health bar i would suggest upping the frequencies of the attacks a bit, as well as add a Flame cloak effect to the Atronach.
The Health of the Flame Atronach should be the linked to the DK's Health or Magicka bar.
The Morphs should still give the same effect as they do now.

For Templars i would suggest using the "Restoring Aura" skill.
Make it summon a "divine being" which will work sort of like the Engine Guardian (has a 10% chance upon skill use to give the user X magicka/ health or stamina).
To make it more of a utility skill, rather than a personal buff i would suggest. That this skill can be used by every ally within the "divine being's" Range.
- Default range is a 12M Radius around the summon, or 18M when using the Radiant Aura Morph.
- When using the Repentance Morph it will automatically restore health and stamina to all allies whenever there is a dead body within its range.
Since it is a pretty strong summon, i would suggest keeping the duration on this skill to balance it out (unlike all other "permanent" summons).
The current skill duration is 18 seconds, which seems long enough already (maybe even shorten it a bit).
