I don't have the guts for PvP, but love the PvE side of this game.
I think Wammo's a great way to start this game. I played my w/mo for about 1 week when I first started before I started a monk primary as well on the back of enjoying that so much.
But the wammo gave me a lot of solo fun early in the game. No need to be level 20 to solo all the Charr on the way to Althea's Ashes, just slap on a 3-pip mending, let energy fully recharge then add balthazar's spirit which will ensure you have enough energy for a breeze, and also helps charge up adrenalin for your attacks. It also teaches you what monks have to look out for (enchant shattering mobs) and gives a little insight into monking which I think a lot of starter warriors do not fully appreciate.
Back then though, there was more fun in terms of pure hack'n'slash, there was no nerf that meant mobs would break aggro and multiple mobs could swarm you and keep hugging you until you cyclone-axed them all to death
As for what secondary to chose later on, it will probably depend just on what you happen to be doing at the time... and for this the ability to save and load templates is a blessing.
