i've had many interesting converstations with wytch in other threads and we agree about many things.
i picked up torrent as an AoE attack but will respec out of it. even tried out EB on the test server to compare. if u feel like u need an AoE definitely go with torrent over EB. biggest reason - costs less end and does similar damage. as a defender u really dont need to be the damage dealer. i mostly use it if mobs get too close. its % chance of knockback is much better than the other powers.
the topic of acrobatics has come up and i think its a waste. all it does is raise your mag 1 level. therefore you'll shrug off the first hold, but the second and every other one that follows will affect you. its doesnt decrease the chance of the mez hitting or even decrease its timer. and its has no effect on sleep or stun attacks anyway. besides knockback resistance, its just hold. seems like a waste of 3 powers to get acro. i even have super leap as my travel power and still wont bother with it.
one thing i definitely like that wytch doesnt use is leadership. maneuvers (+def) is good and tactics (+acc) is great. i'm a team player and the tactics saves me lots of acc enh slots, even my pets benefit from these powers. consider it.
gotta admit, the dark pool was in dire straits when the game was released but the devs have done a great job fixing it. now, between your power pools, the upcoming epic pools and all the great dark choices, i feel there is little room for extra powers.
