1a) Give melee's some love - Remove the absurd penalties from the Silver Flame potions; they cost enough to obtain, are bound to character/account, and the favor necessary to obtain access to them are more than sufficient to prevent everyone from drinking too many.
the negative effects from flame pots are the only thing that stop me from using them constantly. they are needed, and no the cost wouldn't stop me if there were no downsides. money is easy to make if you put your mind to it.
1b) Offer better versions of the silver flame potions at a slightly increased price (one version could offer twice the healing of a regular silver flame potion, while another would heal for about the same amount as a cure critical wound spell, but it would be a sustained effect lasting for a period of time). Also consider producing more powerful potions (such as cure critical, and maybe even offer "heal" potions for those with enough favor).
what you seem to be aiming for is heal scrolls without umd, sure put 'heal' in pots, but put 40 umd on them as well
Beyond universal status ailment removal potions, melee characters with no investment in UMD (which for many classes, is not a class skill) are grossly lacking in self-sufficiency. Should potions replace teamwork and healers? Not entirely, but the playing field as far as who can solo what should be leveled a bit more in my honest opinion (casters should not be the only people who can go into an epic quest, or an Elite shavarath quest, and solo it as though it were a cakewalk).
if you want to self heal, build umd into your character, its silly to think you can make your character fully self sufficient just by throwing money at pots. sure some people already do with silver flames, but they get a downside.
2) Melee will never come even remotely close to half the DPS of a caster, even when it was possible to stack the madstone proc with the clicky (and then have those stack with rage and other effects). Epic fighters and epic barbarians should not be Epic Fail, but Epic Win in some scenarios compared. Enable epic melee classes (monks included) to pick a feat that applies a reasonable damage bonus to their favored weapon.
i read dots(eld+niac) put out about 400dps, add in a few other spells like ice storm and black dragon and i bet your at 500-600dps give or take depending on gear and sorc/wiz, enhance etc. this is well within the reaches of pure dps characters, especially if they have hate on they will hold agro easily against dots. for burst dps situations on small hp mobs, sure casters will win as they can spell spam. but they cant hold that up for long. do you ever see a caster spamming sp at suulo in vod? bet they are out of sp very quickly.
Warriors who have reached level 20+ should, by now, by highly skilled in dealing with large throngs of blood-thirsty enemies (having an AoE crowd control combat tactic would be nice); currently if a melee gets swarmed by mobs, and doesn't have a caster/healer there to lend support, he/she/it is usually either dead, or very badly wounded and close to death (the only exception to this being the Soul Survivor WF build [FVS20], who happens to be a caster good at using a really big sword). Whereas a caster can casually throw down a spell to kill, stun, damage, or stun them in one swift action at minimal risk to said caster.
in my opinion depends how you build your character, i have a dark monk ac build and while my ac is useless in epics i swap on more dps gear, hit a displace clicky, hit shadow fade and start stunning. i rarely take more damage than heal scrolls or even vampirism wraps can deal with. build a toon for it and you can do well
Level the playing field - give us a REASON to play a melee archtype (currently, casters are the best at everything, and thus, for many who are knowledgeable in the game, there would be little reason to actually play a (pure) melee character beyond simple preference and flavor) toward and beyond the first 20 levels.
in my opinion the difference is the stamina behind melee dps as opposed to a casters limited sp pool. the only problem is theres not many places this comes into effect unless the boss has far too much hp.
Thanks for your time.
