I like your Legolas.
I also love your Elrond. However, I would recommend that you return him to his usual 8/4/7 stats, rather than 7/5/7. I would also not remove a threat in the regroup phase (which is too powerful and not in tune with his subtitle) and instead replace it with some other kind of healing, like "At the start of the regroup phase, you may add
to heal Elrond." Or alternatively I'd write him like this:
•
Elrond, Master of Healing Companion • Elf
Str: 8
Vit: 4
Res: 7
At the start of the fellowship phase, you may heal the Ring-bearer.
At the start of the maneuver phase, you may add
to heal another companion.
At the start of the regroup phase, you may add a threat to heal another Elf.
The reason I wrote it like that is because regroup healing is much better than maneuver or fellowship healing.
I look forward to more stuff!
