both are good and fun, seeker may be easier though but all depends on tactic,clasic seeker can be easily avoided by HoS and aps seek can be avoided by kiting, although they can be deadly when they have archangels>voidstep>(unfetter)aps>sacrificial slash>qpqand also GoF on 20 m also heartseeker for locking is nice and gemini slash for hierobugging mages also, switch to def lvl weap if you will, always rebuff when purged - easy, as well as a variety of other usefull stanceson the other hand mystic is good for kiting 1 spammable heal spammable heal buff, physical def buff.,20 % tidal on demon, 700% on sage 3 spark, 10 sec antistun + m atk and crit buffs , spammable stun and 1 spammable silence-there is probably still a glitch when you have to press the other skill to work on pet so this way you can stunlock and kite succesfully, and always keep like 28 m range,so even seek won't hit you...and also alot of usefull plants.
I hate these threads. Just play the classes or watch PK videos and get an idea. Everyone will have their own personal opinion, that doesn't mean you'll enjoy it.
Are sage mystics that powerful? wow
