I wouldn’t like a shorter timer. There are games where you have to think a lot pretty much every turn. If I could only make 3-6 (or w/e) thought through turns, these games quickly become an autoloss. 90 seconds seem pretty fair and sometimes very very short to me.
The option to think turns through is a critical key component of each strategy game. If everyone has to play things very fast, that takes away thinking - and with that deep strategy. Faeria is (and wants to be) a strategy game, not a casual no brainer where you just play every card mindlessly as soon as you can.
Shortening the timer just because some stupid persons are bad mannered and wait for the timer to run out each and every turn, would, in return, take away deep strategy once things get complicated. Yes, there are no-brainer turns. But at least in my experience, most players I’ve seen don’t wait for the last 1-2 seconds before they play these “no brainer turns”. So it’d be a rather small gain (preventing some bad mannered play) and possibly quite a big loss of strategy in some complicated games.
First of all, consider the (very) new players: A lot of them start with the solo content and are a bit hesitated to start pvp. One reason might even be the time limit - they still haven’t internalized the core gameplay, but yet have to face a 90 second turn limit already. Of course they sometimes need to use the full timer before making a what seems an easy turn to a more experienced player. Especially if you’re new to the genre, some concepts of Faeria or CCG are not quite so easy to comprehend. Sometimes a new player might even need the first 30 seconds of a turn to understand what just happened, after a big play, like Firestorm, Triton Banquet or other combat tricks.
There’s a lot to think about land placement. I see a lot of players making horrible land placements, just because they’re too lazy to have a bit of a think.
Once you reach a competitive level, you’ll need that 90 seconds even more often. You can see a lot of that in tournaments. Predicting, what your opponent has in his deck and might be about to draw/play can often be the difference between a win and a loss.
For example, if you play as a control or burn deck vs Three Wishes, once your opponent plays wishes, you have a lot to consider. He now knows the next 3 cards you’ll draw, but if he already played some of them, you’ll know them as well. You’ll want to consider, whether you want to draw one of these cards asap and whether you want your opponent to draw more of them (with the next wish), instead of something else that lurks within your deck. Stuff like that is really time consuming and makes a lot of the thrill Faeria can create if things get complicated. Same if the board gets crowded. Worse, it might kill decks that need a lot of think, because of their versatility.
