Some time ago I made the choice to play Mesmer in WvW, and have been using only her since. She’s level 80 now though, and I need to decide on a build.
I typically join zergs in WvW, although I do roam a bit as well. It’s my opinion that in zergs the most important thing is spike damage since that’s how kills are scored: see someone overextended, and spike him. Because of that the best weapon in my opinion is Greatsword. The GS Phantasm applies Cripple to, making it harder for the overextended person to retreat, and to top it off the autoattack is instant. Other weapons like Staff may output more AoE damage or be stronger in a 1v1, but trying to kill with a staff in a zerg is an awfully painful experience. The damage just doesn’t get to its targets fast enough.
I’m aware that Greatsword isn’t one of the better weapons for duelling and as a result I’ll usually lose 1v1s. That’s fine – I actually feel that many of the videos posted of Mesmers winning 1v1s or 1v2s are largely irrelevant because they take so long to score kills. A 5-minute duel for example is more than enough time for help to arrive for either side, when it doesn’t matter what build either is running. Even a 2-minute duel is too long. I’d rather move around the map and achieve something tangible. I wrote earlier that I roam a bit, and that’s true, but even when roaming I will avoid 1v1s and move instead for camps / dolyaks / sentries / bloodlust.
While I don’t prioritize 1v1s, I do think it’s important to be able to escape a 1v1. If another player wants to fight and I obviously cannot win, I want to be able to run away. On the same note I preferably don’t want to die to Thieves, who are in my opinion an extremely annoying class and for obvious reasons quite common as roamers. I don’t need to be able to kill them. I just need to be able to not die to them, at least for long enough that I can reach the nearest ally.
I have no qualms doing things like changing equipment while out of combat, so if I do use Focus in one of the two weaponsets it’s for Swiftness within combat and the projectile reflects (while out of combat I’ll always equip the Focus for Swiftness, then change back – I haven’t been caught with only the offhand equipped yet). Same applies to Runes of the Traveler or Runes of the Air, etc. If I use them it’s for their effects within combat, not outside of it. Also price isn’t an issue; I don’t mind saving for equipment.
Finally I use my Mesmer for WvW only and never use her for dungeons / PvE / Fractals etc. Any build I use need not translate well also into PvE.
So considering my requirements, how should I build my Mesmer? The only certainties I’m seeing are that GS will be one of the two weapons, and Blink is necessary as one of the utilities. I’m not sure about traits, although I presume GS training will be important. I find I barely ever use the Shatters; the illusions I spawn are just too valuable. I’ve not tried the Mantra playstyle yet, although for the spike damage Mantra of Pain might be good (is it?).
Suggestions?
