I have been seeing so many people complain about the new XP System and it's not a bad as you all think.
First of all I'd like to preface this with, if you really liked STW as a game this wouldn't effect you, the people complaining seem to be mostly players who are only playing the game to complete the Battle Pass, seems like a typical FOMO situation where they don't like the game buy have spent too much time and money where they don't wanna quit and miss things.
Even so there is still more than enough XP to get you to 200 easily. All it takes is a bit more effort. First of all you'll need an endurance of every zone or you could join a discord to help with it aswell, there's many people who are willing to help others with endurances.
So with the guaranteed XP you get each day for playing is 100k, and the daily quest gives 32k and completing endurance wave 15, not even anything higher, daily is enough to get you level 200 within the seasons time limit (70 days being the shortest)
Now if you really wanna go hard you can do all 30 waves and doing that daily you'll get enough xp to get you max level within 50 days. You have 20 days of leeway if you do that and if you only do 15 waves you'll still get enough to get 200 by the end of the season.
You will always have hundreds of incredibly easy BR quests by the end of the season aswell that you could do in an hour and get 20 levels as a last ditch effort.
Keep in mind all of these numbers are to get you to 200 a number you shouldn't even really be caring about, but I guess that what FOMO does.
Finally you can also do the Event daily/weekly, Dungeons gives you 48k a day which is another about 40 levels added, so you can assume that the events are gonna give really good XP.
Broaden your horizons, play different things you can get great XP by doing anything cough except wargames that's the only problem I see cough
Tl;Dr: Join an endurance Discord and do an endurance daily aswell as capped accolade and daily quest, you'll be maxed by day 50/70 (minimum season length). Event missions give great XP too, dungeons gives nearly 50k a day. There's more than enough XP to get 200 by only playing STW.
