So working from the idea of having splats that come out With the WotC ones, martial power is the first so Martial Hero should be our first.

Things I think we should have

Fighter
Overall - Single Weapon Fighter
Powers:
1. Staff Fighters
2. Pick Fighters
3. Mounted Fighters
Paragons:
1. Cross with Warlord - Knight
2. Cross with Rogue - Duelist
3. Cross with Ranger - Staff Master

Ranger
Overall - TH Ranger, SW - Ranger
Powers:
1. Single Weapons

Paragons
1. Cross with Fighter - Staff Master
2. Cross with Warlord - Archery Commander
3. Cross with Rogue - Huntmaster

Rogue
Overall - Bow Rogue (for huntmaster)
Paragons
1. Cross with Fighter - Duelist
2. Cross with Ranger - Huntmaster
3. Cross with warlord - ? (King of Thieves?)

Warlord
Overall - Bow Lord (For Archery commander), Mounted Commander
Paragons
1. Cross with Fighter - Knight
2. Cross with Ranger - Archery Commander
3. Cross with Rogue - ? (King of Thieves?)

Some ideas for Epic Destinies. Not sure if they should be included with the Martial splat as I don't want to restrict them to just Martial classes, but I think they conceptually fit well.

Glorious Leader - for those destined to lead men in battle. Your allies will quite literally follow you into hell.

Iconic Hero - for those chivalrous and valiant few who would sacrifice all for the noble privilege to defend the meek-- think Huma and the like.

On an entirely separate note, maybe we should look at what Martial classes seem to have in common, and try to stay within those guidelines?

Things I've noticed:

-Strength is always an important stat for a class.
-Athletics is always a class skill.
-Most powers have the Weapon keyword (obvious).
