This post is how you can improve hordes in big ways. Long post please grab a snickers.
1] Wave 1 now includes a choice. The initial enemy is gone and replaced with a choice.
2] Horde compass are no longer needed. You can start whatever wave length you want at the horde location from 6 to 10 wave length. Mythic rarity compasses do drop with 11 (95%) or 12 (5%) wave length.
3] NEW chest added for 300 that only drops uniques with at least 1 with a GA. Other chest changed to just legendary items and also costs 300. (You would earn much more Aether in this version)
4] All items drop instantly without having to wait like a whisper.
5] Mythic chest has a 1% chance to appear at end for 1000 cost that contains 1 mythical item. This chest will not appear if you do not have 1000.
6] Wild Cards can appear south of the main choice area. There are 8 wildcards and a wildcard has a 20% chance to appear per wave. Wildcards can be skipped by not selecting them and selecting a choice like normal.
Black Joker - You can make 2 choices this round.
Purple Joker - Get a random option and multiply its effect by 2.
Blue Joker - Start next round with 4 events. Make a choice like normal.
White Joker - Rare joker. Choose all three choices.
Green Joker - Get a random choice and gain 50 Aether
Yellow Joker - Reroll the choices.
Orange Joker - Mythic Rarity Joker. Gain 1 wave length. Make a choice like normal.
Red Joker - Rare joker. Next wave is last wave. Gain 75 Aether. Useful if you just want gear or need to leave!
7] The choices need an overhaul. We have tons of hellborn and elite synergy but other synergy is lacking.
