This is coming from a veteran level 164 bowmaster who has played MapleStory for over 4 years now and have lived through the Big Bang. And I also mentioned this before...
Arrow Blow now officially beats Double Shot. It is better in every way in terms of training. Now unless you are planning to go bossing through first job and second job, I recommend Arrow Blow. And if you really are so insistent on maxing Double Shot then please oh please put 0 in Focus and put the rest in Arrow Blow. Focus is one of the skills I mentioned as worthless from the beginning so it isn't even worth putting points in.
With that said now to move on to your 2nd job. It's fine because you're gonna max everything. Using Power Knock-Back is alright but it is no longer a necessity as a replacement for bow whacking since there is no longer a minimum range for any skills. You can Arrow Bomb an enemy if they're in a point blank range.
Now your third job build. It's good. I like it. Leave it.
With your fourth job build... What the hell. Even if it's not the order you're following, I'll start from the top and work down your list. Bow Expert is fine. It's a core skill. Vengeance... I thought it would be useful but all it has been for me is an inconvenience. It works at the worst times for me with it being level 1 and I assume blasting away any enemy you touch with a mediocre damage skill can cause issues if you are trying to avoid aggroing everything. It's not worth it. Marksmanship is a good skill with it ignoring mob defense and increasing your max HP. I think of it as one of the Bowmaster Core Skills. Maple Warrior is fine if you plan to be that filthy stinkin rich to buy the books by the end of your archer career. You're okay there I guess. Sharp Eyes is fine if you don't max it first. It's not as good as it used to be and I'm guessing it should be maxed by maybe 150 or mid 140s? Yeah around there. Now with Dragon's Breath... Hmm... All it is is a mobbing rush skill. It rushes mobs, not bosses. It's not the warrior Rush or any other character's Rush. It's a regular-monster-only Rush and leveling it up past 21 is pointless. Very very very pointless. It is of no use to you after it gets a 6 mob count. I'm level 164 and mine is still level 1. Hurricane is fine. It's a core skill and your main 4th job attacking skill and should be maxed early. About Phoenix, I don't understand your problem with it. It's better than a couple other skills you wanted to waste SP on. Like Hamstring... Hamstring is the worst of the worst in Bowmaster skills. It is useless. Completely and utterly useless. DO NOT MAX IT EARLY. It should be the very very very LAST skill you are raising. Phoenix is more useful than this piece of crap skill. The little "speed reduction" on mobs is pointless since the mob should be dead really quickly. Okay... Yeah do not get Hamstring. Concentrate is good, but I maxed it after I finished my core skills... Oh. I just maxed it actually. At level 164. I'm starting on Maple Warrior now. You should have 1 in Hero's Will by lvl 160 I think if you plan to HT. It can save your life. Max it at the end of your Bowmaster career.
So in all your plan needs some work. (Especially in learning what skills are good and what skills are bad)
