Guild Wars 2

I am currently lvl 71 grinding my way to 80 (hope to reach it in two days) thanks to eotm and wvw. I know it’s not the best or advisable way to lvl up and learn a profession but since it’s my fifth and last toon to bring to 80 i looked for the “easy way”..
Now
I have done some practice in spvp with average results trying different playstyles but i admit i am far from knowing what to do and what i must not do with my mez.
I am looking for a simple guideline that describes the different “builds” (be it mantra,pu,power,shatter,condi and their mixes) to understand a little more what to do with each..
Basically these are the things i feel to know better:
-when and if i should shatter clones
-when and if i should stealth
-when and if i should melee

For each of the main mez builds

Thank you all in advance

You won’t find universal answers, since it’s all situational!
However, I recommend you reading some of these guides:

https://forum-en.gw2archive.eu/forum/professions/mesmer/List-Find-your-Mesmer-Builds-Guides/first

(My favourite one being Supcuties Comprehensive Shatter Guide)
So many awesome people put a lot of effort in writing these guides, so it would be a shame if noone is using them

Mesmer builds ultimately all break down into the same two categories at the end of it all

1. Shatter

2. Non-shatter

Shatter you will be using F1-F4 for damage or quick buffs

Non-Shatter you will be all but ignoring that you have a class mechanic unless kitten hits the fan and you need to hit F4.

Everything else is situational as to what will work and what wont/ when to do what and when not to. It needs to be learned from Play but its not as hard to learn as a few mesmers want to believe that it is..

Riccardo.7254:

-when and if i should shatter clones
=>Before the targeted enemy dies in a group, since shatters are AoE and killing a target wastes all the shatter potential. Before a boss uses a sure-kill AoE skill in the area of the clone. When interruption is important. When you need invuln, don’t have evades, don’t have sword 2, don’t have sword 4 and don’t have/don’t want to use Blink. Otherwise, heavily situational. Clone builds shatter more often than phantasm builds.

-when and if i should stealth
=>Build dependent, situation dependent. If going max damage, nearly never except certain dungeons/fractals.

-when and if i should melee
=>Whenever you’re confident you won’t be downed.
