I don't know. I can't give accurate estimates on DPS right now. For one, we don't have a memory scraper and I can't be bothered circumventing the game's anti-debugging code (it could be as simple as calling IsDebuggerPresent but I CBA to re-configure olly again to deal with that). Short of recording an encounter and adding the numbers and dividing by the length, we can't really determine it meaningfully, and even so, the presence of even 1 or 2 really nice rad or pen crits drastically changes it (unlike other games like Rift where crit damage was 1.5x base and up to 2.1x based on build, nothing close to 6x like you can achieve in Tera).
I do know that you can approximate the damage on pen arrow with RoA + another ability, but this puts a severe limitation on your mobility (and sucks if the boss moves much) and almost requires being in melee to have access to PBAoE fire trap and breakaway as a viable replacement. Salvo's anim cancel + pen speed gives you something like 2-3 seconds if done properly, which is enough to fit in a trap + volley or a volley + rest arrow if trap is on CD and still end up back at a fast poison -> rad as soon as it comes off CD. The only downside in the rotation is the stun after pen arrow. I'm not sure why people want to remove pen altogether. I'm more a fan of throwing in a breakaway bolt + pen to increase its damage well above rad arrow (for now). I'm trying to work that into a solid rotation that can be used from melee, favoring dropping rest arrow for the BB and a ranged fire trap after the pen arrow instead of a volley, throwing in a melee fire trap before rad since it has almost no cost in terms of time.
At range, I'd never remove pen as you cannot compensate the DPS loss. In melee, I'd actually take advantage of BB to increase pen arrow's damage significantly. If you drop pen arrow, you'd probably lose 15-20% of your DPS in ranged and 20-30% of your dps potential in melee. That's a huge guess, and the variance on those would be enormous because when a BB buffed pen arrow crits from behind with the right crystal build, it hits really, really hard (> 600k is easily possible right now with moderate gear).
