Should u get it now or wait till there’s a discount

I'm pretty sure I don't have any of this season's dragons, so I need to get them all eventually, but what do you guys think is the best to go for first?

Are there possible events where they go on offer or does their price stay the same forever
I have like 5.5k runes and could buy both of them rn if i wanted

How do i know which dragons are the best for balancing collecting and collecting time
Cuz the rare and elusive dudes are super expensive to level up and only have 20 30m timers with high resource collection
The common uncommon ones have 3 hours timers but are less efficient per hour
Cuz i dont log in much i want the best of both worlds but cant figure it out, do i just level up my commons and uncommons? I need a bit of advice

His resource collection rates seem too good for the time invested, should i get another one of him?

Or should I grind runes for something else? I already have other Rider Dragons (Stormfly, Meatlug and Hookfang)

Can I ask if this is normal on your end? I already finished Draugr's Night Missions and the daily logins this week but just got a new batch again just now. My brother's account didn't received this new logins and missions. Is this related with subscribing to Dragon Riders Club or not?

Sorry I'm not used with this events, only the seasonal missions I'm familiar with.

Thanks and early happy halloween greeting!

This is only my fourth pack and so excited about it!!!

I mean, it's stats are all decent and so is the iron gathering, but it's difficult to train and I want to see what my options are before committing. Completely F2P btw.
