After T2 Blunt, should I continue to T2 arts or does my coin priority shift?

Some stats: KL = 100, Elf core with Elementalist and Druid , the rest Hippos and one Fairy

So I just got my T2 Blunt Force and in my excitement leveled that bish up to 105. I'm about to switch out my Elementalist and Druid for a T3 Hippo and Fairy. My question is, should I keep investing in T2ing my 6* artifacts? I am in a good guild and I've got my first few guild pets about 50-100 points away from being 5*, so I wonder if I should sit on my current artifacts or break up the sets to start introducing those?
