Creep Class Items
If you didn't know freeps have new, very rare, gold class item that effect their skills. For example captains have an earring that increases their two arms duration by 4 seconds.
I would like to see this happen for creepside, at the very least via lootboxes. There would be a new type of sigil, that would then be used to barter for an 'augmented trait or skill'. Once you receive the trait or skill it will replace your current trait or skill with a better version.
So for example lets take the WL bubble. If you traded your new token in for the "new" WL bubble you now have a bubble that last 3seconds longer, or has a shorter cd etc. Another example would be to add a 15% chance on damaging skill x to give a self crit buff of X amount for 20 seconds. (just an example, understand the mechanic, ignore the values)
Open to suggestions on a better/alternate means other than lootboxes.
