How so? The ogres are easy to kill for all classes.
If you are worried about potion use just use a man at arms helper since they auto heal after every fight and they will hold agro the whole fight.
You have to kill them one by one which is a lot slower than 5-10 at a time like a CW can do. But yeah they're easy to kill solo and it's still good xp. Questing is pretty fast though, and it's a fuckton less boring. Even though the quests are very basic, I really like the design of the zones, areas, mini dungeons and shit like that. Not everything is a straight corridor, there's a lot of secret passages, mini puzzles(not as good as the DDO ones though) and stuff that makes it pretty decent considering the small size and isntanced nature of the game. Their dungeons are awesome like that too, too bad all of it is mostly trash pack x 15 > boss trash pack x 15 > boss trash pack x 15 last boss, secret technique: summons adds every 33%. For a F2P game I feel their content is very polished, lots of details and shit, which is a bit surprising when I compare to most F2P games I have played(most of which were koreans) which generally involve non descriptive rooms and corridors.
I still haven't spent money on this and it's still not really bothering me, while paying definitely gives you a huge advantage, the difficulty seems to be tuned for people who don't pay unlike what you'd expect, which makes it pretty alright to just fuck around for free. I was very pessimistic about this game and didn't expect to play it but since I was bored I picked it up and changed my mind, I think it's surprisingly good. It's not like THE best game, but for a few weeks of play it's nice, and since it's free there's no buyer remorse like when I grab a mmo, play it for 2weeks then never play it again.
Combat is really good too, somehow. The animations are terrible but once you get used to that it's responsive, fast paced and pretty fun. I still rate TERA's combat higher(at least once you had some attackspeed%) but still very good.
Just did the pirate king dungeon with the most faceroll group, 2clerics, 2rogues and me as a tank. I started using Into the Fray to check it out, shit's pretty cool, gives a massive movement speed buff to the group and makes everyone generate AP faster, can generally get 2 daillies off per pull, shit dies super fast and you can use it to move to next group faster too. Also useful for boss when the healer has adds on him. Tanking is pretty fun in this game, more so than in TERA. The fact you can attack while blocking, that you get a no cooldown charge that also generates aoe mark stuff(for threat and increases damage) and that you can actually solo properly is pretty big.
