Wait what strategy? Tbh strategy is non-existent in high rate servers. Thats my view, its just a total DPS race. Out-DPS someone, ygg, then look for your next target and attempt to DPS it down...
Though personally I played on a private server, liked it for a bit, then again I like it when every class is as important as the other. Something where taking a castle relies on teamwork and fairly long battles instead of a crazily buffed up SinX sneaking all the way up to the emp at the last minute and destroying it in a matter of seconds. Know what I mean?
Well, back on point, virtually no grinding unless you count grinding for certain items or quest items, WoE is sometime quite exhilarating and fast paced, damage flying outta someones donkey, gee not sure what else.
