Mesmer build for "normal" PvE?

I tried running Wastrel's in my flex slot a few nights ago and didn't like the results. Shatter Enchant seemed to be a better fit, especially I was dealing with Dolyak mobs and MoP. Ah well.

Energy isn't a huge worry if you've got a good group. The THK seige was, to quote the monk, more like a meat grider full of Mursaat tidbits. Fights didn't last long enough to deplete energy and the breaks in between were more than enough to recharge our best skills.

I'm tempted to throw Arcane Echo in my build somewhere and mass spam Ineptitude but I'm not sure if that'd work well. Might be too energy intensive.

Your AEcho comment is what I really wanted to reply to. Yes; you are going to see some serious energy issues if you don't bring Emanagers. But, again, the nice thing about most of our energy managers is that Emanagment is a by-porduct of thier effect. Interupt and gain a chunk of energy. Steal energy and gain some back at the same time. Even if you're using it against an ele the dual effects of these skills are nice enough to see play.

GL with it; the echo skills are pure sweetness imho; giving you the option to spam whatever skill you feel the need to use, as you see that need arise in combat.

EDIT: One thing I hate to admit: I rarely bring enchant strips in PvE. I have nothing against them; Shatter E is a great skill. It just doesn't suit my play style most of the time. I don't know why but its never fit right in any pure mesmer build I've used. If the enchantments effect is bad enough that I need to get rid of it, I can usually interupt it (due to a minor Migraine addiction on my part).

Question: do you ever go Me/N? I feel they have better enchant strips than we do, but thats my PvP side talking. I'm an E/Me, so I wouldn't be able to go Me/N. Sometimes (infrequently) I run Air and I farm with Earth, but my preference is full Dom/Ill. I don't get rune bonuses but I try to balance it out by longer sustained casting via EStorage.

I haven't had the chance to try Arcane Echo + Ineptitude yet, but I recall trying Arcane Echo + Arcane Conundrum back in Thirsty River. It wasn't a total disaster but I was pretty much sucked dry of energy when I tried to use the combo. Yes, even with the extra energy from EStorage. Trying to shut down both monks at the same time was the problem.

I frequently bring Shatter Enchant for two reasons. First, I normally play with one or two humans (MM and Ele, mostly) and the rest hench. Thus, I am the only one who's going to be able to shatter at all. Second, while I've become reasonably adept at managing the idiot brigade, getting them to stop attacking a MoP'd target is like trying to get a fat kid to stop eating cake*. It's faster to just shatter the MoP and continue the beating rather than sit there while Alesia/Mhenlo, Claude, and Dunham die trying to tank an invincible target. After all, it all comes down to knowing the mentalities of your group.
