Handling Veterans/Champion’s chasing me in PVE?

One, cripple the target for kiting. Clone Death = AoE Cripple.
Against Melee targets who stubbornly don’t attack my Clones?
With Staff, easy as you just lead the chasing target next to your oldest clone and spawn a new one by either a Dodge Roll or a Phase Retreat.
With Sword, use Leap wait a sec for the mob to run past the Leap Clone while crippled. SWAP, so you immobilize the target and teleport behind it. Swing, Swing, Blurred Frenzy, as you have ~2 seconds before the target is free from immobilize and can turn around to hit you followed by Blurred Frenzy safety. Dodge Roll out, likely causing another Cripple condition and move till Blurred Frenzy and Leap CDs are cleared.
With either, Dodge out of the way of a big attack. This leaves behind a Clone that is going to die and cripple the target.

Against Ranged targets?
I.Warden. I.Warden. and either I.Warden or I.Defender.

Against Large Groups?
Panic, Dodge, Chaos Armor, Chaos Storm, Blurred Frenzy, Decoy, Charge Heal, Panic, Panic, …. did everything die?
Honestly, I do tend to panic in that situation. I try to throw down I.Warden when I can, maybe spawn I.Warlock on any big monster, and make as many blasted Clones as I can and keep attacking. I’m pretty sure its not pretty, but when stumbling into Group Events and all the NPCs are dead and I really want to get to that Skill Challenge …
That and don’t forget to use Shatters for softening all the targets, IF and ONLY IF you can immediately replace the Clones/Phantasms lost immediately.

DE Events?
Dodge Roll through a crowd, Shatter, Phase Retreat/Leap, Decoy, Shatter, Chaos Storm & Chaos Armor/I.Warden, swing sword or use staff until CDs are clear then repeat. All that, just to tag as much as I can. If there is a massive cleaning group? Mirror Images for Shattering helps get off a bit of quick dmg.

i ’m struggeling to handle 3 ettins at once with the build i roll right now

Here’s a link to my general build for WvW and PvE
http://tinyurl.com/mesmerpve

I don’t like switching builds much, so I went with something usable in both WvW and PvE. I use Greatsword and Sword/Focus because I find they give the most versatility in keep sieges and ground battles.

Feedback is probably our greatest tool in ground fights, which is also why I use Medic’s Feedback.

Portal is strictly for WvW, as it has countless uses there. For PvE, I swap out portal for null field to remove that immobilize that mobs in Orr have.

Medic’s Feedback only lasts about 1s though, it’s really ineffective.

Anyway, against large groups you want to kite. Try using crippling dissipation, temporal curtain, and/or phantasmal berserker to apply crippled to groups while letting your phantasms/shatters deal the damage.

but how do i make shatters deal lots of dmg then?
I dont think it deals enough

I use this build here for PvE, and it exactly caters to the style of play I love. It’s so powerful I often have to pull 3-4 mobs just to have enough mobs to last long enough to go into a full rotation. I switch up utilities for what I need, but for the most part, this is really all you ever need. iWarden does a butt ton of AE damage, so after I kite a bit and get them all clumped, I hit magic bullet, switch to scepter, cast iDuelist, cast 3* skill on scepter, switch weapons, cast illusionary leap, switch, blurred frenzy, mind stab a few times, loot my rewards.
