Epic have revealed in a new post over on the Fortnite subreddit that a number of changes will be made to Team Rumble with Season 2. Here's what is being updated:
  • All weapons will now be Rare (Blue) rarity or higher
  • Bandages have been removed
  • Glider redeployment is now a free ability (doesn't take a slot)
  • 150/150/150 materials will be granted at match start
  • Skill-based matchmaking has been turned off
  • Elimination goal has been increased to 125
These will likely make significant changes to the flow of the mode, specifically skill-based matchmaking being disabled and glider redeployment no longer taking up a slot. Overall, they seem like they'll have a positive impact and the community response so far has been good.
One thing to note, as a user pointed out in reply to the Reddit post, is that challenges which require you to use either Common or Uncommon weapons will no longer be able to be completed within Team Rumble. To us, this seems like a fair compromise for more enjoyable gameplay.
