I wish desert were part of the rotation. 6 crit tiles? 
Needs an option for ādonāt careā.
I wish theyād vary things up in general so that we could play in Latveria, Winter, Desert, etc.
And I also wonder why the 5 target tournaments are a long distant memory of the past, excepting SHIELD.
Too many stored retaliations?
I avoid the forest because itās harder to color block the enemy.
They really should mix it up a bit. If only so that people donāt become reliant on environmental strategy for matches. Though I will admit to being fully guilty of going forest sometimes with a boosted character simply for the quick 5 AP.
Huh, Iāve been playing this game since the release and just realized you can choose the environment. I feel like an idiot.
Where can you select that option?
Do you get a choice, I thought it was random
There are three buttons when choosing your fight. The left is the forest, the top is the danger room, and the right is the NY streets.
Been playing since the beginning and I didnāt know this. Seriouslyā¦thanks. this is really helpful! 
Shocked at how many people play forest. One bad cascade there can wipe your whole team, especially in LRs.
Forest is the one I avoid, for exactly that reason; of the three listed I slightly prefer City because itās the most neutral.
Before they nerfed criticals, playing in Forest or Tech was fastfastfast because with the right character (coughMagnetocough) you could generate crits fast and furious, letting you easily get lots of environmental before the AI.
I finally figured it out on my own a couple days ago. Someone should put this on the āI wish I knew about this my first dayā thread.
But matching forest tiles quickly is almost like using boosts. With the environment bonus from tournament buffed characters, one good five match (or two three matches) on forest tiles means 5 of every color from thorned rose. If you get unlucky and start on a red-scarce map itās a great way to get your Ragnarok going for the quick win.
I just play. Since the changed the crit tiles, I donāt worry about the environmental tiles. Itās very, very rare that I get screwed by the forest level.
The best way to see what arena you will play in is by looking at the back-picture on the 3 heroes that you is going to fight (When you choose your opponent, at the screen that you can chose to skip).
There you can clearly see the trees from the forest OR the computers from the Danger room OR the buildings from NY OR the Latveria castle, etc! (And ofc the places remain the same for the nodes, so the top will always be the Danger room, left will always be Forest, and so on).
forest is best if there is no buff or a small buff, since you can ramp up AP faster
danger room is best if there is a huge buff, because the crits will do a bazillion damage.
I actually did not know you could select your arena. I almost always chose forest since it is the nearest button and you can press skip fight button faster. Actually it is pretty bad place to fight since some unfortunate crit from the enemy team can really fuck you over. Especially with boosted characters. I think maybe NY might be safest since the heal does practically nothing and AI might waste turns getting special tiles.
Same here. I pay far more attention to what team Iām fighting and how many points theyāre worth than which slot theyāre in. On top of that, I will often jump between spots, hitting āskipā while I build up a set of a few choices to fight, if Iām not sure whether Iāve found a good fit yet.
I use OBW, so forest is great for me even if the enemy gets Thorned Rose off. It makes the fight much faster since I get the AP no matter which one of us gets there first.
