@ Josip & in general, from having played both mesmer and an "easy-mode" engineer in WvW.
Background: I have my engineer, lvl 80, in full exotics, mostly Berserker with some Valkyrie thrown in, Scholar runes, specced 30/10/0/10/20. I throw grenades. Shoot my rifle. Die hard. Go 1v1s and 1v2s and generally run with my guild to good success.
It's mostly fun, it's rather repetitive and the idea is simple: kill people. zone out zergs. abuse superior range and perma swiftness. provide a few useful combo fields for my squad.
Now, my mesmer. My mesmer is level 50 (started it last week). I run a GS / Sword+Focus or Staff / Sword+Focus.
Decoy - Blink - Portal - Feedback - Veil. Currently 0-0-10-20-10. Damage is lacking and I would not go against most lvl 80s.
First off, somewhere in this forum I watched a video of the laziest glass canon spec you could do for mesmer - 30/30/does/n't m/atter, in full bersker + scholar runes. I believe the player never switched away from greatsword.
Greatsword 1 skill = rifle 1 skill.
Greatsword 2 skill = grenade 2 skill + clone + hitting more people generally + buffs
Greatsword 3 skill = as good as any grenade and they will not have time to dodge.
Greatsword 4 skill = grenade 4 skill + more damage and better chance to hit
Greatsword 5 skill is for playing tennis with the enemy.
Now, take mesmer utility - that player lacked some of engineer's range but had more battlefield mobility than an engineer. It had better escape skills. It does more than enough damage to destroy non-tanky people from 1200 range.
Imagine if he had played with sword/focus off-hand.
Sword 3, if you get in range = better version of rifle net shot, which normally misses unless you knockdown or CC the player in some other way or he has depleted his dodge bar and is close.
Sword 2 ... you know that with that glass cannon spec it'd be ridiculous.
Scepter 4 (and GS5) are the better CC version of Rifle 2 and I'll not even talk about knocking people off cliffs or walls or them being aoe yet.
Scepter 5 - more on that later.
All in all, I can tell you that playing a mesmer in WvW can be about as effective as an engineer and you should not feel underpowered unless you choose to be.
That said, this is not how I'll play my mesmer.
My spec will likely be based around Chaos / Inspiration / Illusions with toughness+vit+power(+healing+conditions) gear.
At level 50, with some quick decoy/blink/veil etc, I already sneaked my squad through a broken down wall, a bridge that had 6 arrowcarts firing on it, up a jumping puzzle and on top of garrison, where the Invaders were defending garrison with said arrowcarts. Mesmer is hard to stop when he decides to go somewhere.
Later that same day, I dropped down, blinked in middle of enemy zerg that had siege up at cliff edge and attacking same garrison @ inner gate, waterside and knocked down 8 people with focus 4 and GS 5. They died. We wiped the remaining members.
Since mesmers are "hip", there's quite a few alts and mesmer 80s in our guild atm. It used to worry me, but always having 3-4 around has made things interesting.
3xmesmer portal trains into supply camp from tower.
Porting people back for a quick retreat.
Dropping down cliffs and porting your squad down, as most of them are not running falling damage trait.
Blinking through zerg, assaulting siege weapon (warden - traited to reflect - is a nasty, nasty thing to cast on a catapult/balista) then porting back.
YES, portals do fail sometimes and YES, organized squads can shut down your group as you appear, if you're not prepared.
However, it is fun, it is useful and it is not a gimmick, as much as you feel like it, Josip. Portals = mobility.
If you're running with a guild, focus on being useful and train them on how best to utilize portal and your being fast, mobile and somewhat tough to kill.
If you're running by yourself, by all means, grind yourself a glass cannon spec - the escape utility is there and the damage is as good as any and unlike Meteor Shower or grenades, people can't just step out. Run with a zerg/larger group and focus down smartly. You have enough utility to not die easily and you'll rack up enough loot bags to be more than happy.
P.S. I run Feedback Medic trait and pop down next to a corpse / downed player every 10 sec just to get the bubble up. Is it effective? Not always .. but it has a psychological effect - people back away or stop firing. As for the actual feedback utility ... Try to get a few mesmers together and chain it on keep/tower doors that are being attacked.
