Even with a high end PC you'll get lesser FPS, there are some maps and weird spots where you gonna get shit fps, you'll probably need a VPN too, depending on your location and ISP, you'll gonna have bad time connecting to the launcher from time to time. Even with good Internet package, 300+ ping is my usual ping, there are certain time of the day that I get less ping 150 ~ 250 ping, you'll have to get used to it, pretty decent.
Game mechanics wise, tons of bugs with no fix because we dont have the source code, if you plan to stream throughout your leveling phase you'll have to bear the defeaning silence, you'll rarely see a single soul at any time of the day, if you do, it's just some asshole camping newbies because they suck at pvp on higher level map. Imo if you wanna stream then you would be better recording or livestreaming NB and AK or maybe some BG.
Prepare to invest atleast 33k AP for your pet and pet chips, throw in a couple of more to sell for some quick gold for your actual gears. Give SB a try but dont expect much, probably the only players you'll see are those people who love and enjoy the game prior it's official shutdown.
Bonus tip: If you have tits then your best option is to pick Free knights faction, there are lots of simps there who are more than willing to assist you for a little attention and some UwU, someone is bound to send you an unsolicited dm on discord anyway.
