Hello!
I strongly recommend to change class, because archery is a vain project for new players. Carrying a bow makes you target of other ranged players, and 95% of these are better than you, to a marginal extent in personal skill, and to a significant extent because their characters are 4-6 levels higher than yours. You could of course argue that you are gifted and you will fast be at least as good as other archers at aiming, footwork, awareness and tactics. But the level and loom advantages other archers have still make you easy prey. Traditionally and game mechanics wise, archery is a high-level choice.
My observation is that archery becomes playable at 18/24. It is a somewhat reserved statement, because I am aware that every build has to fulfill the needs of the individual player in the first place, and in some cases, people might perform better with different builds. However, since 18/24 is the preferred choice of most of the veteran archers you will encounter in this mod, it is applicable. Using the 18/24 build, if you are level 30, it means you will max out WM and PD, and put the residual 3 skill points into ATHL. You will be terribly slow instead of slow (LVL 31 - 6 ATHL) or quite slow (LVL 32 - 8 ATHL) because quivers are heavy and you usually spawn 2 of them. But at least you have decent accuracy due to 8 WM which you fully put into Archery WPF and decent damage due to 6 PD, provided that you have a MW bow (+2 damage, multiplied by 6*0.14+1, and additional accuracy).
If you have 18/21, you aren't accurate enough with high-tier bows. If you have no MW bow, you can screw most fights against other archers and trying to kill people in MW armor sets will be a pain in the ass. You are probably playing from level 1 to level 31 and then retiring, so you will never hit the level range where archery becomes competitive. As long as you only collect looms instead of going high level, I would not recommend to play archery at all. If you still think that archery is your class of choice, it is probably best to reach generation 16 for full exp bonus and a nice amount of LPs with any class but archery, and after the last retirement you level up your archer.
Understanding the different bows is not really relevant before you have a high level archer, because at low level, archers are pretty unplayable in general, no matter which equipment they pick. The benefits of the Rus Bow become obvious when you have about 185 wpf in archery: The crosshair will be significantly tighter compared to the Bow. But since your archer is low level, has a build that gives you less accuracy than the community's favorite choice of 18/24, and you haven't loomed your bow yet, this and other differences will be obfuscated by the beginners' illusion that archery is a strong and fun class to play. Archery will be fun and competitive when you reached higher levels than 30 and use MW bows, if you accept that you will never be really fast because of the quiver weight. But before that, it is probably the worst class you could choose unless you want to become very frustrated.
You will probably wonder what to do now since you already played till level 30 and don't want to respec. My recommendations are
1) Use a Longbow and play DTV, slaughter bots until you level up. OR
2) Play Siege and hunt other ranged players with a Nomad Bow or Tatar Bow. These bows have better accuracy even unloomed at low level, so you can get some nice headshots against players who have light or no helmets.
If you live in NA, playing Siege will be no option because NA2 is dead and EU2 has a high ping. In that case, just join EU7 (because NA7 is pretty much dead too), because high ping with a Longbow against bots doesn't make much of a difference. If you live in EU, do the EU2 Nomad Bow or the EU7 Longbow trick.
I hope it helped a bit.
Have fun and good games
