In original fallout games, you have some perks that can make you a specific HtH fighter (Silent Death=assassin, HtH evade=pure unarmed). So based in that pseudo classes i have some suggestions for this game that can make HtH builds more interesting.
Assassin build:(supported in fallouts games by Silent death perk)
Perks:
Backstabber: any melee attack made in the back with small melee weapons (knifes,ripper) has a +5% critical chance and 15% more critical factor.
req: lvl 15 80% melee. suggested pic:
Silent Death: melee attacks dont remove the sneaking status, but reduces your sneak at half (until the combat cooldown its over)
req: lvl 21 110% sneak, 110% melee or unarmed.
Like I suggest I the sneak thread, this effect (reduction of sneak but dont lose the status) also applies when you are hited sneaking.
Berserker build:small support by original fallout games: adrenaline rush (useless perk), and die hard in FT.
New Trait:
-Berserker: when hp are below 40% you enter in a blind rage and you can ignore the pain, you gain +10% DR*, +2 DT and -2PE /as downside any healing made on you heals only 50%, and doctors checks has a penalty of 40% .
*optional:+5% DR and ignore crippling.
Perks:
-Adrenaline Rush: +3 melee dmg and +1AP when hp are below 40%.
2 ranks, req: lvl 15 EN: >5 ST >5
Karate-unarmed build:Maybe a special quest in san fran to train with Lo Pan or Dragon (a player can only train with one of both) and gain some special unarmed attack (punch or kick) or some bonus.
Perks:
Smashing hands: when you hit a target with unarmed weapons, he will have a -15% DR.
HtH evade: need to be reworked to be useful (and need to work), but I think AC need to be reworked first:
http://fodev.net/forum/index.php?topic=4592.0Other suggestion:Bonus HtH damage should add +3 melee dmg but only 2 ranks (Its a great sacrifice use 3 perks for +6 in max dmg)
and also can add +2 dmg for thowing weapons (not grenades).
This are suggestions for new perks/traits based on builds, that doesn’t mean that there will be classes like other RPGs. You can combine any of the suggested aspects to make the build that you want (Berserker unarmed, unarmed assassin, etc).
