Monday evenings (usually around 1830-1900 Central), there's at least a group if not a BG running around New Frontiers. Try giving a /region shout out in NF. And of course, ask politely. Friday evenings (again starting around 1830 Central) there's usually a public BG forming in NF. Usually led by Aquilonia (Warrior princess).
If you are still looking for a guild, there are several good guilds on Gaheris: Legendary Mercs are definitely one.
Now: What's this "slam tic" nonsense?

As mentioned elsewhere, max your Enhancement and Rejuv (50-50). My tic, Fraydon also has Flex (25) and rest in Shield (13). Add a range macro (/macro range /groundset 1400). When it's under the feet of your target, you should be Just Right. Then practice on blues with the various damage spells. There's shouldn't be much left of one by the time it gets to you. Some (Flex) melee to finish it off. Rinse and repeat. Fray has no problem with a moderate group of orange and yellow, or even a handful of reds.
And reading Rehtul(Kiraniri), reminds me, the tic's uninterruptible is unbelievable against a ranged mob (archer, caster). You'll kill them long before they can kill you. Once again,
a tic is a caster that just happens to have fairly decent combat as well.
Regardless of realm and class, the
armor you get doing the quests will do very nicely as you level up. Do them in the Tutorial up thru level 10, then let the quests lead you to the subsequent training towns. You will level
very quickly. Quest weapons; not so great.
However: The new Pictish Invasion camps
http://vnboards.ign.com/daoc_general_board/b5176/115964946/p1/?20 give good weapons. They can also be sold to merchants for good cash. If you have a blue weapon, find an appropriate camp, pull solo Picts from a distance -- be warned, given a chance, they will call for help. You want one far enough the camp won't hear them. Farm until you get the yellow weapon (and shield?) you want.
Welcome back.
