I've solo'd several melee to 60; mostly solo'd a warrior.
The key to solo melee is three things - Regen, AC, and Strength - in that order.

AC - Mitigates more damage; goes on a sliding scale with regen to determine what you can and can't solo.
Strength - The more strength raises the amount of damage you do; it also raises your attack rating which means more hits on mobs and an easier time landing hits on higher level mobs.
Regen - The absolute key to soloing as any melee.

This is why I suggest rolling an Iksar. Slap a fungi tunic on him and get some Kiva's pots for post lvl 20 - the 11 dmg shield at 20 starts to pay dividends for the 6 min / 40 plat a charge usage. Especially when you go for an AC build and are getting hit for low amounts of damage. An extremely high AC build with good regen will allow you solo 3-4 mobs at once at lvl 30, in say Mistmoore, greatly speeding up your leveling rate.

Key droppable items for an AC/Regen build solo warrior -

-Fungi
-Gem Encrusted Ring - 10 ac, 7 str - far far superior to a 6/65hp ring as a solo war
-Horn of Hsagra - Shoot for a Swiftblade of Zek MH and a a horn offhand. 35 ac is superior to the 15 str, 25 hp you loose off a BoC offhand
- Lodizal Belt - to go with a CoF. The 2 regen and attack beat the 9ac/5str you'd loose from a blood runed girdle. Regen is the only thing that beats AC in this build.

No Drop items (if you have access and DKP/plat to spend):

- Orb of the deep sea - 45 ac. Enough said
- Rocksmasher - 47 dmg 41 dly. 35 ac. 41% haste. If you're going to use a 2 handed weapon, this is pretty much the only one I'd use in this solo build. You're loosing 10 ac to a swiftblade/horn of hsagra but gaining 5% haste. From level 25-40 or so it will likely parse a little more than BoC/HoH; in addition you get less repostles from mobs with a 2 hander. This is a blessing in disguise though - if you have the regen to mitigate the dmg you're taking, less repostles mean less damage shield dmg the mob takes, lowering your DPS output.
- Velious quest BP - Meh. You're going to spend 14.5 seconds clicking it for 58 hp. In those same 14.5 seconds, you'd regen a static 38 hp (sitting) with a fungi. Most of the time when I play a solo melee, if I have to regen a bunch of dmg I'm going to use that time to afk (no group responsibilities can be nice). Sometimes though you'll be talking to friends or whatnot and the 20 extra hp every 14.5 seconds will net you about 83 more hp a min.
- Ring 10 - If you got the dkp or plat and you're all in on a solo warrior this is a great way to go
- NToV Warrior quest armor - AC, AC , AC - particularly the bracers (25 ac), boots (32 ac) and Vambraces (33 ac)

Thats about it. I believe in AC/Regen over HP as a solo melee because you shouldn't ever be going below 15-20%. What good does an extra 400hp yield if you're always above 20% as a solo war? Not a damn thing. If you are going below 20% consistently, you're fighting mobs that are too tough for you - you're not landing as many hits on mobs dealing that much dmg relative to what you could be landing on a slightly easier mob. Faster killers will always equate to faster experience.
As a melee, HP only really matters if you're in a group getting CH'd or you find yourself playing poorly and consistently dropping below 20%.
