Guild Wars 2

Hello,
recently I have returned to game and I am looking to spend some good time playing it as the game is really great. Only problem I have is making a decision what to pick :-). As Guardian is my got to pvp class, I am looking for something that will get me through pve farming, world completion, gold farming and similar stuff. It should have good mobility, survivability and be somewhat fun and melee.
I have narrowed my search to these 3 classes – Reaper Necro, Scrapper Engineer and Revenant.
Reaper Necro – seems like good survivability and damage, can get perma 25% speed, good AoE for ranged marking of mobs, leveling will be probably pain
Scrapper – Engineer really versatile, hammer looks good, perma swiftness, leveling also pain
Revenant – good damage and survivability, perma swiftness, playstyle feels like boon auras in Glint and autoattack, Shiro teleport and quickness boon – > autoattack

What is your personal experience with these classes?
Thank you for your time and insight

Necro lvl 1-79.- I don’t really like necro, it has nice survivability, nice mov speed(with the signet) and minions are cool, however, people often says that you get discriminated in dungeons and such as necro
Reaper.- even though i do not like necro, i really enjoy reaper, mostly for the new shroud i always hated the ranged shroud, for the matter of being ranged, i mean, if you cant die, whats the point of being at distance, melee just feels better for me. Also Reaper seems to be really useful in raids, but that’s just me.

Haven’t tried scrapper, but engi is cool once you get your kits, mostly bombs. The weapon skills suck doe, i hate them.

Revenant.- Good damage, good survivability, he feels great, problem is mobility, even with shiro, and like Perma dodges(there is a shiro skill that gives you one extra charge of endurance, while evading backwards). But i hate moving around the map with revanant, its just painful. This might be cause i am used to playing thief/warrior in open world so..maybe its just me and my l2p issues, i’m just not used to it yet.

Herald.- mobility problem is fixed with the perma swiftness thing, and facets in general are great, perma fury is also pretty cool, and you wont get discriminated in any kind of pve content.

So, IMHO,based on what you asked for, run revenant…leveling is funnier for me with revenant, because its a new class, and i actually enjoy unlocking all of its features slowly, taking my time, unlike necro, which i already know all of its skills, and basic features. Didn’t really like my engi, i deleted him and created a mesmer instead.

GL on your choice
