Playing on trial accounts

[Zub]

Hi all,

I sometimes feel the itch to multibox again and trying to think of ways that wouldn't cost me anything :-)
Since i'll most likely only be playing about 3-4 hours a month, i can't justify 5 subs.
Heck I have a Keyclone license so i don't think i'll even resub ISBoxer.

With that in mind, i plan on maybe creating 5 trial accounts, and play toons to 20 for fun.
Probably melee toons this time round (never did a melee group before)

Some questions:
- Trial accounts can't invite. Is there ANY way i can keep my toons in a group forever (even after logging off), so that they can quest together?
I can probably get someone to create the initial group for me, to get everyone in the same group.
Would converting the group to raid before logging out work? then converting back to party after loggin In.

- Can Trial accounts enter battlegrounds? use the Random dungeon finder?

- will Jamba work on trial accounts, or do they have limitation with chat channels and such that would prevent jamba from working well

- what melee class would you recommend (for levels under 20)?

druids: not sure they are very interesting at that level. or 4 bears maybe
rogues: probably not too easy to MB
RetPaladins and EnhShamies: probably a good choice, and on top of that i can probably do some instances with them
warriors: probably easy enough to MB

I'd like to use a single race for all 5. if possible Alliance (i've done alot of horde in the past)
so it looks like a dwarf paly+4shaman team, or 5 gnome warriors lol

Any input appreciated.
Thanks,
