my thoughts:
if you are really dead-set on taking tactical training leadership, at least put the +perception proc in it. on my bane, where i regularly fight level 54 tsoo/BP/CoT in astoria, the only situation in which i have ever needed to use tactics was in PVP, and even then only for the +perception
build up ONLY needs the gaussian proc + one or two recharges to taste, you can get the set bonuses from gaussian elsewhere more effectively
six-slot tactical training maneuvers with reactive defences, you want the 8.75% recharge and 10% resist
five-slot heavy burst with superior spider's bite for the +10% recharge. you DEFINITELY want the global toxic proc as well as the 10% recharge
five-slot venom grenade with superior dominion of arachnos, you want the chance for -damage and terrorize
diamagnetic interface is not that good, take degenerative radial for the -max HP and toxic proc (which even fits thematically with SoA)
support hybrid is not that good because of the 50% uptime, take assault radial for the global doublehit proc
recall friend is ok but you can get 999 prestige teleport powers, get super jump instead so you have some actual vertical mobility
