If you want to increase aspd. Why not increase the rate of doppleganger card instead. You argued that doppleganger card in this server doesn't not add on much aspd compared to other server. In addition, they did boost the atros card before ( damage, not the aspd ). As atros card user, the current rate met my satisfaction. And if you don't want to sacrifice more slots for atros card. Increase your agi thn. :P As simple as that.
Back to the argument of ship captain to replace fhelm or limited helm. If the atros card rate increased, obviously people could save a lot of stats from agi. For example, breaker ( thana user with f.dag ) will have around 80± agi to make the aspd 195. Sinx Crit build will have around 60± agi to make aspd 195. Therefore, they will have more status points to play with, status points for agi will be add on to str or vit. :) One of the main reason why I am still using a limted or fhelm is because of the aspd + 10. And tha captain ship hat is FREE. Limited helm will cost like 2.5k± and fhelm 40 tokens?
Bout the cards you mentioned, Abysmal Knight card ( increase damage by 25% ), Orc Skeleton Card ( increase damage by 20% ), Desert wolf card ( increase damage by 15% and +5 atk ). Atros card ( increase 100 atk ). Well, let's use some example again, sinx (thana user with f.dag) will have around 2.5k atk. Let's say they use the cards mentioned, 25%+20%+15% = 60%. 2.5k * 160% = 4k. Sinx with thana, abys, orc skeleton, atros card will have 2.6k * ( 100%+25%+20%) = 3.77k. I know that it will be more complex. I am just showing the differences by replacing atros card with one of the card.
Increasing the rate of atros card MIGHT lead to some problems. There are other problems aswell. But I personally like this the most. So I am just sharing 1!
1) Demand for kitty claw increase. People would reduce agi ( flee rate decreases ) when they use a atros card. And this wut happened when you have low flee rate. When you are walking in for_fild01. You will hear "pew pew pew pew" and the next second you are spinning on tha floor.
