Well, right now my biggest problem is the mesmer
But how do you manage to stay alive? that is my biggest problem. Is it a question about the right gear? Or just moving at the right moments to avoid the damage? (When you used up all of your endurance).
Truth be told, most of my gear is of exotic quality – and it will take a long time for me to upgrade it, but if that is the answer to most of my problems, then please share your knowledge
So just a general thing, in general melee attacks are stronger than ranged attacks, so it makes sense for mobs to be more dangerous in melee range. But a few mobs actually are the opposite, and their most dangerous attacks only happen when you are too far away from them.
Back to mesmer specific gameplay issues, mesmer lacks a solid melee weapon set. We don’t have a single melee offhand for core mesmer, and we only have 1 melee mainhand or 2handed weapon (that being sword). So again, no surprise you seem to find melee much different than ranged.
Mesmer is actually an incredible survivalist, its just that its relies on active defenses instead of passive defenses, and being a light armor class it does take more damage from mobs than say a warrior would. Your core defenses (and for this I will leave out chronomancer line, as I don’t know if you have it or not) are your 2 dodges, sword 2, staff 2, Blink, F3 (also called diversion), F4 (distortion), GS5, and in a few cases Torch 4 (the Prestige).
You are going to rely on a mix of evades (dodging, Sword 2), invulnerability (F4), interrupts (F3, GS5, Focus 4 chained skill), and smart positioning/kiting (Blink and Staff 2), and occasionally stealth (mainly Torch 4, though you have a few other stealth skills). You can also use reflects (Focus skills when traited, and Feedback)
You will always have access to F3 and F4, and you should always be running mainhand sword in PvE, so you will always have access to Sword 2. Its a 2.5 second evade on a 12 second cooldown, that’s incredible for PvE, really. Use it to evade a big attack you know is coming. Most mobs in core Tyria do not have breakbars, feel free to use interrupts on them to interrupt attacks. In newer maps (HoT maps and LWS3 maps), a lot of mobs have breakbars. Use your evades, positioning skills, reflects, and invulnerability as your defenses on these mobs.
The biggest thing you can do is to learn the tells for each mob’s attacks. Learn when you need to dodge to successfully evade the attacks, learn when you can eat an attack to save your defenses for a bigger one that you know is coming later, learn how to best use your positioning skills (staff 2 is excellent for getting out of AoEs, used incorrectly its also a great way to get inside of AoEs….). Don’t be afraid to take the inspiration traitline for extra survivability (healing and cleanse a condition on every shatter). If you want more help with mesmer, I suggest you make a post in the mesmer forum, there are better mesmer players than I am in there that can help you more.
