Koss vs. Melonni

ill trust the tested build off of an official fan site over the opinion of some "experienced" player because you say i should take his word for it. i will take the word of the majority of players over the word of one because some stuck up prick says he is experienced and i am childish. this is the internet dumbass, im not going to take the word of one person because you say he is experienced, im going go with what most people are saying and guess what, its not what you are saying. save your fking insults for someone who gives a shit, because i dont. Many PvX builds aren't "Tested" very thoroughly, and since they can be publicly edited, are often defaced, or modified from the original build by someone else who thinks they know better. It's not a bad place to get an idea, but don't accept what it says is a good build for it's word, as skills are often updated, and the templates rarely take that into account unless it's a total nerf.

Alex may be rude, but he's often right. Melee Heroes and henchmen are less useful than most other heroes and henchmen due to targeting bugs, so they are less usefull than a similar ranged or caster build. A Melee hero or henchmen will run around after a single target instead of attacking, won't change targets well, won't disengage when being kited, and only occasionally shifts targets when being blocked.

Warrior heroes/henchmen are useful for carrying Charge if you need a party speed boost, but otherwise not particularly exciting. Minions work better for holding agro and body blocking, Paragons and Rangers can do similar amounts of damage per hit as a Warrior or Dervishes but can change targets with little movement so they attack more often and they're just as durable, and Assasins are just plain awful as dagger sins (even with the AI fixes, they can run Critical Barrage fairly well though).

However, if you had to chose using a Warrior or a Dervish, I will generally chose a Dervish hero, as they tend to be "less bad" with their skills, deal with enchantment cycling fairly well, and can (and often do) get more than 1 opponent with each attack with the scythe. Energy skills are used better by the AI than Adrenal skills, and Dervishes are all energy (with built in energy management to boot).

Now, you asked for other people's opinions of which one is better, and that is what most of us have offered. In stead of telling people trying to help you to shut up and answer your question, perhaps you had better clarify the exact question you want asked.
