I haven't played in a while and was wondering if anyone could give me their opinion on para gem on twink gear?

Which item would be best to gem? (Gear, necklace, ring, weapon)

Would it be a waste because gear would soon be outdated with next event? (Like tarlok gear vs druid/spirit )

I know its a gamble but want to hear others opinions thx. Idk if it matters but im lvl 22 mage with all types of gear for options.
