If you really want to be ready for Summer I advise you stop rolling from here on out and pray that there'll be a lot of event between this and summer.

Presumeably Raikou will be back as Summer servant and if the patterns hold then Summer event will introduce new servant in bulk, and every servant they introduce are above average.

If you're not so interested in Summer servant tho you can safely roll for Raikou, She's pretty good IMO so it's not a bad deal.
