Guild Wars 2

The question is about stats in armor/weapon/trinkets.

Which stats are useless and which stats are good?

I mean, is there any good way to use PVT Set (Soldier/..) and be good in game/ enjoy the game?

For example, Full berserker set looks like some kind of challenge, but is it the right option?
——————————————————————————
I am only PvE player (no WvW or PvP)

I got about 18 characters slot and 2x characters from all professions, but I am not sure, which gear should I get them :/

Raids are opened and I think, soldier set doesnt looks so good in participating in raid run.

Q: Which stats/settings/ are good/the best

I have full ascended armor/trinkets with legendary weapon on my elementalist (Tempest) and I am not sure about it :/

I made all ascended pieces in Soldier set and there is big Question, if change of stats to another one is good idea.

Isn’t PVT (Soldier/..) only about surviving for players, who are new at GW2 mechanisms, isn’t PVT set only about forgiving some faults made by player?

I mean, soldier doesn’t look for me as rewarding set.

The only atribut for damage is Power, nothing more. That doesn’t look rewarding.
Conditions/Buffs/Criticals => Toughness/Vitality doesnt help me in fight as well, isnt it true?

Questions:
1) Change ascended sets from Soldier to another set ->Berserker,CondiBuild,….
2) Are Soldier stats
a) rewarding?
b) good to use?
c) so is this set really for beginners? Because the only reward is longer life and few more faults before death → If I want to get out of easier play and want to be better player (use all of opportunities to get the best results), isn’t the best idea throw all PVT stats equipment out?
3) About 18 characters are good opportunity to have
(for example: 1 Elementalist – ConditionBuild; 1 Elementalist – Berserker)
So aren’t some stats useless? I mean, my first idea was 1x Soldier, 1x Zerk and I think, it is stupid idea now.
4) Finally, so which stats are good to use? I am really not sure

Answers:
1) For pve – try to change them for pure dps stats depending on u build, one-two item(-s) per step to get used for “fast and squishy” gameplay
2) Are Soldier stats
a) for pve – nope, tough and vit are good in pvp/wvw, remember that more tough means more chances to grab agro from monsters
b) as newbie pve stats, see answers 1 and 2a
c) begginers, tanky-builds and pvp/wvw
3) all depends on time/money u can spent for game, more chars require more “resurces”, so…decide yourself depending on real life situation
4) decide build u wanna use, then think about stats. For example ele is very versale class, u can play power dps, condi or support…
