Question on tats

I have a question on what tats to use on my ISS when it hits 95 don't have any right now .
most of the time I did the normal k90's tuna ****+q etc and I solo grind a lot but once I hit 95 I think I should go full support class don't think going solo once I hit 95 will get me to far.
What you guys think is sword+shield and con tats and health sa good setup for me.

typically strength.
it gives you better chance for skill double/reuse.
also lets you do a tiney bit more damage.

if you wish to be more defensive go with +con.
maybe + con and get yourself a shield.

but skill doubling is always appreciated.

STR doesn 't effect br's double duration on party members
the only skill you would like to have on double duration is chaos symphony(99 skill), the rest you can spam always
both STR and CON are good for solo, all matters how big train u can make :)

i had str build - nice dmg
i had con build - verry big survivability (w/o shield)
both builds can aoe good, but safer is second
