prob not worth it, game is literally the same as cn in most if not all ways (shitty progression and gacha) so theres prob the servercheck too. also devs are glazing the whales with a ton of benefits so if they complained a little there might be a banwave.
yea, extremely unfriendly to f2p in my opinion, even if u get lucky u can only clear a few more stages. you also need dupes to make s heroes useful, for example, ling has an 8s shield skill when someones hp is low, awk 1 immediately removes that time limit, and awakening 3 gives more shield with hp recovery (takes a lot of pulls to go awk 3)
