Light Fighters Need Low Cooldown Shields, High AD DPS, Mobility, Some AOE, and Low HP Pools
They need to split, they need to skirmish, they need to duel, they need to tank *some focus fire before they die, but most importantly, they need to fucking die when you hit them with cc.
Thats why I would give them low cooldown shields that scale with dmg and lvl. A low cd shield will soak dps periodically and really help you in a skirmish, but cant save you from burst dmg. I would also make their shields moderate to high in size, but low in duration.
