Melee is extremly strong ( close to OP in my Eyes ).
My Friend and myself play as a Warrior ( He ) and a Mage ( Me ).
The Difficulty is normal, but only because its a bit faster hard wasnt a problem either.
We are now Level 14 and we both have Lone Wolf und Class Cannon.
So we only have our 2 Characters instead of 4.
Thanks to Lone Wolf + Class Cannon Speed is useless. We both have 7 Speed ( 5 + 2 from Equipment ) -> 18 AP per Round ( more than enough ).
The Strategy is: He has a Two Handed Weapon and kills the enemy Mages und Archers instantly with 500-1000 Damage Noncrit ( 1000-2000 without Armor ) or 1500-3000 with a Crit.
I CC Enemys ( Fire Wind Earth Mage ) and Deal around 500-600 Damage Aoe with a Single Attack ( Way Less than him ).
BUT he can use Rage Mode ( + 50% Damage ) and i can use Oath on Destruction ( Level 1 Witchcraft Spell ) on him also +50% Damage -> Whooping 1000-2000 NON CRIT Autoattacks and he has 4 of them every Round.
And that Equals 1500-2500 Whirlwind Attacks und around 10K DMG with his Quadra Attack.
He can also Lower the Armor and Resistances of Bosses -> we nearly Instakill them.
+ Man at Arms Traits -> 50% Magic Resistance ( Mages are useless against him ). Thanks to this he has > 100% Fire Poison nearly every Magic Resistance -> I can heal him with my Fireballs and so do the Enemies.

BUT he cant tank Shit because Enemies dont focus him but me and im a Class Cannon with > 1500 Life thanks to a Maximum of 15 on every Stat.
So i have 15 Int ( skilled ) + 1 Know it all + 7 Equipment => 23 Int and he has around 14 Strength ( with Equipment ) and still deals Tons of more Single Target Damage.

And to the Tanking Problem -> Summon Elemental -> Elemental gets focused -> Heal it with your Spells -> Much WoW.

In the End im a Supporter and Aoe Damage Dealer as a Caster and a Melee is 110% pure Destruction on Everything everywhere.

Melee has no Weaknesses in this Game except for Range and thats were Featherfall comes in ( Port your Melee next to the Enemies ).
The Melees dont even need Spells to slaughter Everything but yeah they are way to weak...
