Here are my ideas for few mounts.
Mount name: Gingerbread Man (Or Papa Ginger Jr)
-Speed 20 (Maybe 25)
-Ability: Gingerbread Man is able to do simillar slam like normal Gingerbread Man do. It would deal 25 damage trip and push foe's. It would have 10 second cooldown to keep everything somewhere balanced.
To not make this a boring mount I would offer new addon, passives!
Gingerbread Man Passive: There is 10% chance for this passive to aqiure. It would work like this. If you die, there is 10% chance of getting revived. Upon being revived you get:
-Infinite Stamina for 15 seconds.
-You lose your mount for the rest of the round.
-There will be a side-effect. It has 45% chance of happining. After infinite stamina end there may be a animation where character may or may not start to being sleepy and doze off. After that, you will be not able to move for 6 seconds and you can be hurted for few seconds. (I just think removing mount would be not enough)
-Does not work in PvP or Melee Smash (Also, President has 0% chance of getting revived)
Other idea for mount:
Cheese Cat (I wont start to talk about it, most of info is already on the Wiki)
-Ability: Freeze. After holding Mouse 1, Snowman Mount will do a small animation. In his range a massive storm will happen. After doing so everybody in it's range get freezed and aren't able to move for 7 seconds (Does not work in PvP or Melee Smash). You will also gain a speed boost that lasts for 10 seconds.
The last mount will be:
Mount Name: Present Bot
Ability: Present Bot has 2 abilitys that player may choose to use.
First Ability: (Activated by pressing F while mount is active) Stamina Boost. Every survivor in your radius gain Infinite Stamina for 10 seconds. The cooldown lasts for 3 minutes (Only 3 charges)
Second Ability: Healing. Everybody that is in your range will get fully healed (Simillar to Flag or Acorn effect). There is only one charge for this ability.
This mount will be more like a support for your team.
Those my are ideas. What do you guys think?
