The Porcine F2 skills dig up items for the player to use. These items are similar to what a thief can steal. It is almost next to useless since the player has to press the F2 (1 second cast time), wait for the item to be dug up (seems like another second), press F to pick the item up (this takes some time as well since the pet is most likely not next to you), and then actually use the #1 skill (which is another 1/2 second).
The QoL improvement would be to instantly put the bundle in the players skill bar upon pressing F2. The player could then immediately use the item without going through all the steps described above.
May not be a simple change but would open up some smoother gameplay and could create some interesting tactics in PvP.
