Here are Aegir’s problems:
- He is a free tile sync. Can endlessly set off his special while he is on defense and it doesn’t matter.
- He gets his flanks killed (in part because of point #1 above)
- His special does no healing on defense (or offense). This is basically why point #1 is true. Only maybe against red Titan does his heal do anything. On raid offense his special is too short and if you have enough blue tiles to benefit from the heal you would easily win with any other blue.
And so to fix it is not simply adding more turns to his special, or extending the buff to the whole team or even really a +defense . Something needs to be done to eliminate #1. Either do something meaningful with the heal (whole team damage/heal, damage taken by Aegir and protected allies for 3 turns converted to a heal over time for 3 turns, flat HoT added to existing effect, heal on special damage) or add some bite the the special (riposte, steal life dot that rotates on enemy, etc).
