Didn't mean tab-target as actually using tab key to get your targets, but as a naming for a combat system - you know, choose your target, spam hotkeys. No aiming required.
Oww, I see. Never heard tab-target before tbh. And you won't survive either with spamming hotkeys
L2 is much more than that but I am biased anyway.
Actually, there is one class that has a lot of spamming but... different
Anyway, really loved that game for it's open world pvp system. You can fight wherever and whenever you want, except inside cities. No instances, everything is up for grab by the stronger one or the first one which makes nice fights for boss drops or other collectibles. The whole approach is good fun with a very balanced class system.
...but
it's not good for solo play. You can certainly do 1v1 but mostly that turns out in FFA last man standing which has its charm
Otherwise you always want a 3 player party with DD (Archer/Mage), Support (Overlord preferably, always has been my class and I was good
) and a Healer (Bishop or a very capable Elven Elder).
