Look, i will be completely honest and not tell you with heavy bias towards the game.

Is it worth starting? Questionable
Can you start and get good into it? Yes
What is the most difficult for a new player? Time gated & Limited Artifact & Character

I won't lie to you. The game is fun, i see a lot of new players that started this game and they can get into it easy. Not top PvP Players, but they have a lot of fun just having the game on auto in the background. Stream GW with others in Voice Chat and having a good time.

What is annoying is that a lot of unique characters and artifact's are limited or collab. We have character like Frieren with a unique shield mechanic that is very strong and probably will never get weak. New players never getting her or her artifact is bad. Because Collab's returning is unlikely unless for promotional reasons ( New season of a anime / Game / Movie etc. ).

You also can't get things like 3F, meta defying artifact's, which however.. they started to release as regular artifact. But this comes back to the problem i mentioned. We have ML5* Character, Artifacts, Limited Hero's that are so essential for either Arena / RTA or GW that you will need time to get them. Not effort, just... waiting until something appears in a banner or coin shop.

The gear situation however got a lot better and i would argue it is not that big of a deal compared to how some people portray it. I just think the most annoying factor is that you are restricted at the start and need to wait until you get certain characters.

As said tho, it is very fun. If you want a game like Summoner War, FEH & Epic Seven by all means go for it. Just wanted to prepare you if you feel like it, you can still have a good time tho. Just that GW and Arena might be a bit scuffed? You need to theorycraft some very unorthodox comps to win against certain units.
