First off thanks much for all your suggestions and tips.
@xonation: thanks much for the ui tip, while I did not grab the duration timer, I did rework my whole ui to make it appear more clean since I can't play with a higher resolution than 1280x1024, so new spells kept reducing my free space, which is now much better : )
So what first turned out to be a pretty weak class at the lower levels when not twinked with masters and good armor, now kinda started to impress me. After farming some nameds I managed to get my important skills to Master I with the rest being Adept III (lucky me even managed to find Master I Dominate and Master I Enraging Demeanor : ) (dropped in mines)). With my current level (mid 50) and items this class started to shine, it really seems that coercer gets an incredible boost for his levels and the equipment he got. The main reason for the level I believe is the mentioned durations of you, along with the high resistance chance of a skill being solely adept I. With this being my first char still having much to learn, even I now manage to kill two blue ^^^ nameds with adds at once, or staying in the middle of an orange mob camp mezzing/stunning the mobs while picking them one by one without taking a downtime. Even caster nameds are no problem. I really have much fun playing a coercer by now. Also teaming did improve, I can keep a named mob stunned for the whole duration of the fight, yesterday we even aoe killed mobs without healer. And it did turn out that even a good team can once come in a situation where an enchanter can save them from a whipe. Along with the power regeneration I offer, I do feel to have a class which is liked to be seen in a team.
There is still much I have to learn from playing a coercer, but from what I currently see I'm really far from considering a reroll 
The only thing that I don't like is the changed way charm works by now (but I believe I'm not the only one thinking that way). It is just sad to see my pet run off while I'm in the middle of a fight.
