Guild Wars 2

Hello guys,
after a month away from solo join and playing team pvp (with my guild mates) today i tried some solo join to test few builds…
this is what came out (which is really different from what i usually see in tPvP):

1) every team has 1, or more, decap engineer… really?
2) every team has 1 necro (fear spammer, how many fears does a necro have? …i got something like 10 sec fear once… maybe there where 2 necros…)
3) usually when you see a thief… just look at enemy team and you will find alway 2 or more thieves (i just player a match against 4 thieves -.-’’ really?)

and above all i’m sure there are a lot of hackers i’ll explain:

- today i played against a bunker guardian… now i have a guardian and i know that guardians can stack aegis but … how many aegis does a guardian have? 2? 3? 5? well i was 1 vs1 against this guardian and after 3 mins of match he was still blocking my attacks (looking at his buff i saw aegis stack every second, does exists this kind of skill?) getting 0 damage and attacking me in the meanwhile… his damage was hilarious but when you cant hit your enemy for 3 mins also 1 dmg/sec is enough.

- also i played against a thief… a particular one. I don’t have a thief but i know that their skills are based on initiative… but now tell me: how many time can a thief use hearthseeker before run out of initiative? 4? 5? 10? well… i was chasing a thief and you know warriors are really fast to catch enemies… after something like 1 min i was still following this thief which used only hearthseeker to run… really?

-the last one comes from an hilarious warrior which was able, apparently, to stack aegis… repeatedly, really? a warrior which stacks aegis? which skill? we was 1vs1 so no guardians around and above all he was able to dodge every my attack after i landed them… looking at animation i hit them but after i land my attack (animation complete and all) he dodged… and he dodged 90% of my attacks (the other 10% was blocked by aegist multiple stacks) -.-’’

it seems that aegis hack is becoming important… did you had similar encounter?
