Return of Reckoning

Hi everyone. I need some help from you.
Would like to get in here and would be up for a tank. Preferably on the destruction side.
However, to be honest, I don't know which one to start with? Chosen seem to be the most represented. Are the BO and the BG just as useful?

Current iteration of BO is bad so ignore it.

BG has probably the highest skill cap on destro.

Chosen is the perfect starter tank and core tank in all groups.

Thank you.

Sorry for the doubled posting.

Unfortunately I have to ask again. The BO is really that bad? So I like the playstyle so far. Would love to play a big orc. Maybe I should check out the Choppa after all?!
The Chosen One is quite nice to play. But the spark doesn't fly. I just don't feel like standing there afterwards and I'm a useful bucket full of stones.

If you are not gonna be joining any halfway decent groups/guilds that care about party setups, if you're primarily going to be solo queuing scenarios and cities and joining pug wbs only then pick whichever class you like.

If you plan on getting into groups/guilds,
1)playing in warbands for largescale RvR, then pick chosen.
2)playing in small groups, ranged party setups, 6man style then pick chosen or blackguard.

Currently BO is very underpowered compared to its Order counterpart.

I see. That was a detailed explanation. Too bad about the BO. Thank you
