L1 Revives in solo event milestones moving forward
The common theory for why L1 Revives aren't in solo event milestones anymore is that there isn't enough room to display everything when you include a bonus reward to them (like rift shards). Thus, one reward needed to be removed to make room for the extra reward. This remains a theory because no one from Kabam ever commented on this. Kabam, please comment on this.
The suggestion: moving forward, if the need arises for an extra item to be included in milestones and an existing item needs to be removed to make room, please don't take the L1 Revive away. My suggestion would be to get rid of the 20 3-star shards. I'd even rather give up the 3-star signature stone crystal than lose the L1 Revive again.
Between energy demands being at an all time high (extra long event quest, rift quests, infinity trials) and time commitments being what they are (dungeons are time-consuming, arena is currently the biggest source of gold in the game), it's incredibly difficult to carve out time to try to farm revives on story quest, which still isn't a reliable way to go about getting them. Removing these revives from solo milestones are really alienating Free to Play players.
