RDM lost some of its visual identity with the upgrade to Veraero and Verthunder III
RDM's visual type of spell-casting is defined by using rapier and focus in combination to hurl spells at the enemy.
However, the animations for Veraero III and Verthunder III (which are upgrades acquired at level 82) do not fit the hurling motion our character makes. The particle effects, while good-looking, only really appear on the enemy. Nothing is being hurled. The supposed impact suggested by our character's motion falls flat. There is no momentum or sense of direction to these quite frequently used spells anymore and as a result, RDM feels less satisfying to play after level 82.
As such, I would suggest adding parts of the regular Veraero and Verthunder animations to the upgrades, namely the black and blue lightning beam for Verthunder and the wind orb for Veraero.
