Not Bad, Underdeveloped Character Appeal
getting the damage/speed enhancing gladiator skills and going all agility for using a bow is the fastest killing build for both bosses and gaining exp.
For a 4 spectrum in an rpg or mmorpg i think it's best to set it up like this:
1. A tank class with damage ignoring passives, and the strongest single-target skills, which must nullify strong attacks in order to gain rage points in order to perform its skills (ideal for anti-boss b/c he takes FOREVER to cooldown his attacks, although he's invincible when fighting mobs he can't really farm)
2. A mage class with aoe spells with passives that make the spells slow the target down if it's hit by them. This class would be the absolute best farmer and would thus have to return to town and stay at an inn in order to regain the points needed to cast the spells. Maybe this class uses awake points.
3. A cleric/vampire class with constantly regenerating magic points and mp regenerating passives that uses healing over time and damage over time spells. This class should be designed for farming small amounts of higher level mobs, as it must take small breaks after each battle to regain all of its mp. the concept for this class is you can cast spells with no cooldown, but you can't cast them twice on the same target, as in you lock onto like 3 targets, and although you're being healed and hurting them at the same time, you're running out of mp very quickly and can only sustain it if your bars are high enough capacity to allow it before you die.
4. A summoner class which can pump out a 12 clone army, but can only make them 10% of their original strength(enemies of the same level or lower only) and each time he summons them he consumes a very expensive food potion because he becomes ravenously starving at giving birth to his swarm, and needs his children to make daddy proud by pillaging a rich mini-boss so he can afford his gambling lifestyle. This class's appeal is for semi-rare loot farming. You'd only be able to truly advance to tougher areas after equipping your summoner with a full set of decent items (might have to sell an ultra rare item for the gold to afford potions). The summoner being equipped with an item means his minions are born with those items too. The summoner progresses through the game fairly easily, as does the cleric, but both will risk being killed and penalized in the process, with the summoner sometimes uncertain of whether or not he can defeat the next story-boss or not, and the cleric being uncertain of surviving a faster way to gain exp.
Each of these classes has a unique social appeal for the type of play style and group interaction diversity there is to offer. the tank can answer requests for specific emergencies and save the day for noobies or close friends, the mage can hang out in party leveling and chit chat, the cleric can organize party questing friend's list adding, and the summoner is everyone's auction house coordinator. I mean, there's only so many types of variables for storing information on a computer database while being entertained in the process of entering data into it.
