Y'all have reading comprehension issues. They're not splitting waltz timers. In fact, they're kind of merging them even further.

I'm no COR expert, but let me show you an example of what's going on (we're going to assume the user has at least one merit into Loaded Deck.):
A Dancer just used Curing Waltz V and is also waiting on the recast timers for No Foot Rise and Presto.
A Corsair uses Random Deal.
Now:
Random Deal will choose one ability from this list to reset a timer:
  • Curing Waltz - Waltz Timer
  • Curing Waltz II - Waltz Timer
  • Curing Waltz III - Waltz Timer
  • Curing Waltz IV - Waltz Timer
  • Curing Waltz V - Waltz Timer
  • Healing Waltz - Waltz Timer
  • Divine Waltz - Waltz Timer
  • Divine Waltz II - Waltz Timer
  • Presto - Presto Timer
  • No Foot Rise - No Foot Rise Timer
Out of a list of 10 entries, the Waltz timer will be reset by 8 out of 10 possible choices.

Here's how the proposed changes would make it work:
Random Deal will choose one recast timer from this list to reset:
  • All Waltzes - Waltz Timer
  • Presto - Presto Timer
  • No Foot Rise - No Foot Rise Timer
Out of a list of 3 entries, the Waltz timer will be reset by 1 out of 3 possible choices.
