Currently the summoned weapons are only used to maximize dps by casting them, using 1 or 2 skills and imidiately dropping them again. They are underwhelming to use, at least for me, and I feel like the weapons could be a lot more useful.
So my idea: Delete all the utility version of the weapons, and rework the Fiery Greatsword elite into a new "Elemental weapon" elite. The new elite would change it's shape every time you change attunement and turn into a fiery greatsword in fire attunement, frost bow in water attunement, lightning hammer in air attunement and earth shield in earth attunement. The point is to rework the weapons into a strong combat elite. I also thought it would be nice to add some pulsing boons to it, since the weapons don't apply boons and especially ice bow falls short to water's theme of healing and cleansing. Idea: Pulsing might and fury in fire, some heals and regen in water, swiftness/alacrity in air, protection/resistance in earth.
Now, with that little rework, we have 4 unused utility skills left. Feel free to suggest anything, I thought simply placing the most used spells of the weapons into these slots could easily make up for the loss (= Firestorm, Frost Storm, Thunderclap, Fortify). However some new skills could benefit ele as well. Some ideas:
