Yes, finding groups for TI is still possible.
It's even easier right now because of an ongoing exp event (will end after next maint). Thanks to this there also are some Nogg2 parties - try your luck in Juno!
And wow... so few Vit and so much luck. x_x
Looks like it was supposed to be a Crit Whip Wandy with autocast?
No idea about that build to be honest.
SR needs a bow (you cannot switch weapons while SR is casting) and Dex/Agi to boost the damage. Some Int for sp pool and Vit for some survivalibilty. Luk is better saved for later levels.
You can check if you still have a reset from the Mesmerist in Eden (behind the counter) to adjust your stats for free if you want.
For some more info about SR build (stats and you can see some gears) you can check this thread here as well as irowiki for a stat build you can follow. The thread is a bit older but the info is still accurate.
You might want to pick up a pair of Emerald Earrings instead of Sound Amplifiers though. They each give +5 Int/Dex/Agi and if you maxed Lessons you get an additional +5 to those stats: easy +20 Int/Dex/Agi!
Very awesome to boost your damage and help your casttime.
There also is a set with a garment called Elemental Towel that is supposed to boost SR, but last I heard this was buggy, so better stay away from that for now.
