After playing the seasonal mode for a while, I want to share my feedback. The idea is nice, but the execution has room for improvements.
There are five pointers where the seasonal mode can be improved:
1. Unbalanced
2. Forced
3. No creativity
4. Grindy
5. Long and boring matches
Unbalanced
First of all, I immediately thought Lippy would become a problem, but, interestingly enough, I actually rarely need to use him, only against other Skellige players (ironically). However, even without Lippy, Skellige is still the problem in the equation. The idea of the seasonal match is to create a new rule set with new challenges. But this set favors Skellige too much and there isn't anything other factions can do about it.
Forced
When you want the (cosmetic) rewards, you are forced to play the seasonal mode. There should be an alternate way of completing the nodes for those that do not want to play the new mode. Does that defeat the purpose of the seasonal mode? Not really because those looking for a change are still going to play it.
No Creativity
The Unrelenting She-Bear poses a new way to gain victory. You do attack the opponent's bear or focus on buffing yours. The idea is nice, but there still isn't enough room for creativity. Slyzard eating the bear is cute and all, but that rarely leads to victory. Making creative events that aren't
solvable games is tricky, but I would like to see a bit more variety. I'll also discuss this in the next paragraph.
Grindy
The quests are just grindy and uninspiring. The win 3 matches in a round is especially a HUGE mistake and should be removed from all future seasonal events. Like mentioned in the paragraph above, the seasonal mode lacks creativity. This also applies to the quest nodes. We need more unique win conditions.
Long Matches
The matches are pretty long and, more importantly, quickly become boring. The length of the match is inherently a problem, but it could at least become more interesting when the issues in the previous paragraphs are solved.
TL;DR
The novelty of the seasonal mode wears off quickly because of the long and boring matches that lack room for creative solutions against an unbalanced army of Skellige warriors, where you are forced to grind to unlock the (cosmetic) rewards.
One of the possible solutions:
