NOthing too long just a simple review during my almost 2 month use of osu
The main point of my use was the relax feature for all modes. it did not disappoint me whatsoever through my entire use of it, the only issue I had was mania which after a long break in the song the relax bot will always miss, dropping the combo, though i went an entire month without getting banned and reached around 50k without mods and such.
The warp feature is very, very high risk to get beaned of off osu, test it out in multiple accounts to make sure, CTB was the first gamemode I decided to try, my account was 3 months old, ranked 1900 globally, S multiple songs above 5-7* stars legit until i decided to use the time warp, of course to make it less obvious I decided to use HR with some plays or played AR 10 songs to seem more legit, took around 2 weeks for my account to get beaned.
After taking roughly around 1 week and half I leveled up and ranked up another account using only relax throughout my gameplay, reached to a high rank without a ban and I can confidently say that the relax bot is one of the mods to use unless you decide to make it obvious by one day deciding to FC extremely hard streams a day after you seemed to have gotten an A on a 2*, go at it a safe low level and make your way up and I can say you will make it super far in the rankings.
