Frontier Coins -- Who should I buy?

[Feajy2]

I have 825 frontier coins for now and thinking about mythical box, but im affraid getting 5* star character like Alliance General. From frontiers i have already:
- Trooper Eddie
- Eternity Eddie
- Lady Azov
- Bastion
- Warlord
- Wrath
- Sentinel Lilith

Also have 135/150 Eternity fragments (probably Beelzebub or Claire in). My question is to wait for further events or buy box or Eternity character/ Lilith?
