Your acc is pretty decent with sol and titania, 2 really useful SSR. "More SSRs" doesn't always mean a better acc. "Which SSRs" is the question you should ask and not "how many". If you got 4 of those kind such as Tyr, u won't be happy with them.
Sol and titania are both very flexible to use. If you start rerolling, I don't how long it would take to get an equally good acc. Don't forget you have to grind from very beginning too.
Trust me, you are not unlucky with your acc. There many lv80+ out there, who play this game for the whole time and haven't get a SSR kami with jewel draws yet (kamiless weapon + Eidolons u know how it works...). The small amount of jewels u have spent says nothing.
Keep grinding with your current acc, gather jewels and event weapons, choose a kami through miracle ticket depending on what you will have got over time.
If you really want to reroll, then start rerolling when belial or more 100% eidolons getting released. They will be the only reason for rerolling, because they will make your SRs as strong as SSR or even stronger.
