Ok, Basic run down of the Light faction stuff out so far, and what I can make out as the best way to run them (in my opinion of course, there are lots of other ways I am sure

)
I won't give stats as they are posted elsewere on the Forum.
Evangeline = Only has standard attack. Abilities let her grant extra Armour, give bonuses to attack and Defence, Heal, and detect hidden foes. Needs to stay pretty close to the action for most of her effects to be in range. Generally needs protecting, although she has a pretty good defence she has no armour, so if a hit lands she will die.
Kronen = I said Evangeline needs protecting? This is the man for the job! This man is a Tank (in the CoH sense of the word

)Good Defence, great armour and lots of hit points! Only has a Basic attack, which won't hit very often due to his low attack value, but when it does hit, its gonna hurt! He has the best Basic Damage stat so far. His special ability is an uber-counter attack (+4 attack +2 Damage counter if he dodges). Once again showing he is best used to Defend.
Khaine D' Lacreu= Bit of a mixed bag. Average attack values, good defence and armour, average hit points. Abilities allow her to grant a re-roll and take damage from an attack for a friendly model. She also has a +3/+2 attack that deals x2 Damage to Dark Faction members. She can pretty much fill any roll as defender or attacker, especially when facing the Dark faction!
OverallCurrently lacking a good stright forward "beat stick", the Light Faction may find mixing in a hard hitter from the Neutral Faction helpful. Evangeline is the Nexus of any Light faction build, her Holy Armour spell (which appears to have limitless range!) Can make any Friendly much harder to drop (Kronen becomes nigh on unstoppable with Holy Armour and the supernatural Armour equipment card, making his armour stat 10!)especially if Evangeline keeps healing him!!
So far the Lights lack any ranged attacks or aggressive effects (e.g Poison, Doom etc etc), once again making some Neutral Faction members useful.
Its best to protect Evangeline at all costs. Kronen is best used as a Charge blocker, and saving his action couters to make his special counter attack on any would-be attacker. Activating Evangeline last seems the best way to use her. She can then keep her action counters to defend herself from any attacks that slip past the blockers. Once its her turn, she can use any actions she hasn't used to Heal and Buff Friendlies, and as she was the last to go she will be re-charged of actions (for defence) before your opponant can get an attack in! With carefull management (and some Neutrals

) The Light Faction can wear down any opponant.
