A stronger but slower class most effective with melee weapons.
Starting stats
In the beginning of the game, mercenaries are clearly the best. For levels 1-10 focus on getting hybrid to max. With max hybrid both mage and bounty hunter attacks will do relatively nothing. Coupled with some OK strength, just hack away at your enemy. You should have a relatively perfect record if you use this method. For bounty hunter just leave hybrid as physical and for mages just switch hybrid. From 10-20 you should stay in 1v1 and mostly likely the best method is strength. Strength build with FC and a heal along with max hybrid should make for mostly all wins. From 20-25, 1v1 gets considerably harder even with hybrid and I only recommend getting lvl 23. You should still win most of the time. Once u get lvl 23, buy Mjolnir. You can choose to stay in 1v1 to 25, but you record WILL suffer. What i recommend is to become a support mercenary and go to 2v2 until lvl 31. When you do get lvl 31, you should have amassed quite a bit of money to make yourself a strength build. Buy the up to date current items and follow a strength build and you should do well!

Skills
NOTE: all these builds require at least 101 health, I will not address high HP builds because they are simply moderated stats of the current builds. Generally, equipment wise, it is good to have physical weapon + energy aux + energy aux OR [energy weapon + physical gun + physical aux] <--- Recommended
As I wrote in the passage above, mercenaries REQUIRE max hybrid. There is no option to it. So far the only types of successful mercenaries are strength, support and sometimes tech. Strength and tech is generally 1v1 and support is generally 2v2. Strength builds generally tend to distribute points as max hybrid, max FC, 1 berserker, some in heal and some in intimidate. Strength builds need OK strength (unless your not using FC, then you need relatively high strength), 40-50 WITHOUT stat modifiers. You also need good DEX because you NOT want to block a ton. Tech + your stat mod needs to give you around 20-24 resistance and support should be decent. Tech builds generally have a max SS with high tech. You can choose to play a bunker along with it but it hamper your play because you need so much manna. With this high tech and hybrid you have a very nice defence. Have 101 hp and 59 manna (or more if you are using bunker, but not recommended). Use weapon, gun and aux to get their HP down and then use SS to give them a ton of damage and take their rage. If you have bunker, rage it next. For the skill tree, if you are not using bunker, have max SS, max hybrid and 7 heal. Rest of the points can be anywhere. The level-7-heal is for 2 heals instead of a max SS.
