As title stating - Blinding Light(Flashes/Searing Light) was iconic templar defensive skill, it was also only class AoE skill. Effectiveness of it was equal to NB's Fear - as both were AoE CC that could be used offensivly or defensivly, Sorc's Streak - defensive AoE CC with damage component, DK's Scales - close combat version of it that allowed to equal odds when outnumbered. Removing of this skill was equal to removal of those skills above from other classes and was a huge loss in class defense.
It was covering templar's worst problem - stamina sustain.
Pros: 1. 50% miss chance meant saved stamina for block 2. 50% miss chance meant saved stamina for not using Break Free when enemy's CC was missed 3. AoE component made it very usefull when outnumbered vs close combat stacked enemies, thats why with current pvp meta where enemies stacking with 24 people most of time this skill would shine. 4. only class AoE CC that forced enemies to break free. 5. Apply debuff on enemies - it means you could cast it in mobs in pve and they would be CCed and as healer you could safe mana from less healings needed.
Cons: 1. to cover all pros this skill works only for melee and was absolutelly useless vs range enemies.
There was several reason (as ZOS claimed) why it was removed: 1. it affected strong mobs in PvE that should be immune to this skill. 2. In PvP people didn't understand why they missing target.
Based on those 2 factors Blinding Light could be returned but a little bit revamped:
1. It could be implemented into revamped Radiant Ward morph of Sun Shield to increase morphs diversity. This morph will become AoE CC (maybe with damage dealt like Searing Light before or Flashes' pulse) while other morph BS - damage shield with AoE damage.
2. It apply any sort of CC(knockback/knockdown/disorient pulse/stun) in 5m radius as before and play role of melee AoE CC. It can also either deal AoE damage like Searing Light or pulsing like Blinding Flasses to equalize morphs and make skill equal to same skills of other classes:
Streak can deal damage, serve as escape and apply AoE CC;
Talons can deal damage, apply AoE CC, give synnergy, apply dot;
Fear can apply AoE CC, speed debuff and damage dealing debuff.
3. One of best aspect of it - Miss Chance removed from it and instead revamp other skill:
- Eclipse - revamped into self buff that absorb 4 projectiles. So it will allow to save stamina when outnumbered by having defensive self-buff for both magicka/stamina builds, while templar will have AoE CC.
Eclipse visual - currently Transmutation set 5pc bonus have only 1 effect however animation aplly two different visual effects: yellow aura glowing and blue strings. I think it is unlogical and visual weight of it is too high. Blue strings could be removed from this visual and instead added to revamped Eclipse, so it will be easily noticable by enemies when templar is under Eclipse effect buff and visually will oppose same red strings from NB's debuff.
