The various classes/heroes of GE are namely: Elementalist, Scout, Musketeer, Fighter and Wizard. Lets look at a brief summary of the classes.
Classes: 1) Elementalist: Has 3 types of magic attacks, Lightning Ice and Fire. Specializes in pure attack magic and aoe. Weak defense though.
2) Scout Healer cum Buff cum Attacking hero. Basically your support hero. Will be wise if you consider this one of your main heroes.
3) Musketeer The ranged hero. Uses guns basically. Able to wield rifles and pistols(dual-wield).
4) Fighter Hes your tanking machine! He can use guns, daggers, swords. He has a cool stance which lets you use a gun and a sword together!
5) Wizard Mixture of attacking and defending spells. When you reach level 60, you can levitate and meelee monsters cant hit you! Well, provided you can last that long.
Combinations: Well there are a lot of combinations out there that vary according to your playing styles. Lets look at some of them
3 Wizards Not recommended if you are not well funded, pots and early leveling are a chore.
3 Musketeers Heard that you can get to level 50 in 4days with this set. Pots are a chore though.
3 Fighters Quite good, but the lack of heal(From Scout) will be a factor to consider. Will have problems getting ksed in afk exp.
3 Scouts Why would you need 3 of these? You would have trouble using aoe spells cause they don't have them(I think)
3 Elementalists Not recommended if you are not well funded, pots and early leveling are a chore. Will have problems if too much monsters are coming even if you have AOE spells(Spells have cooldown)
Musket Musket Scout The combo I'm using now. Quite easy to die if I didn't use aoe spells when a large group of monsters come. But very good at afk leveling.
Musket Scout Fighter Same as above, but you have a tanker =)
Musket Scout Wizard/Ele With a aoe caster and a musket to finish bits off, its quite an efficient combination.
Fighter Fighter Scout Will get ksed by Afk Muskets and can't hit air units. Generally good.

Tips: 1) Enhance your armour/weapon! At the shopping street at your starting city. Find the enhancement boy, forget his name. After enhancement, your weapon will be stronger than the next 2 weapons you will be changing. Eg: Level 10(Enhanced weapon) =70Att Level 18(Normal Weapon) = 66Att
Enhance only 4 times though, after that and you might fail the enhacement and lose your weapon.
2) Press space bar for "Afk fighting"
3) Use the city guide to get around the city quickly and the waypoint to teleport to locations(World Map).
