Dragon is replaced completely by bahamut in 4th job. It needs to be level 15 though. Long door timers are useful in a large number of scenarios, so door should be maxed. Doom isn't considered useful, but I'd dump my points in that over dragon, however it's purely personal preference.
I haven't used Doom once yet and I'm a 107 Priest. It's really just for fun and not useful for any training or bossing situation I can think of. I haven't used Summon Dragon either, but that's because I just wanted to max Dispel.
If you ask me, both are pretty useless and i've never used niether of them (including bahamut) all my stay in mapleroyals.
Would u say its more useful to put 15 in dragon and 1 in doom (for fun) then put points into magic armor or w/e that 1st job skill is I know it's not much def with that skill just kinda thinkin on alternatives
I maxed door and dragon. Not once have I ever used doom. I put one point into it. Even though dragon is replaced immediately upon 4th job I liked having him float around with me til then I wouldn't bother with the 1st job skill it's negligible. Put the points into whatever you want - you'll never use any of the skills you decide to dump the points into again anyway once you're 120.
I have used Doom (back in EMS) and it's a lot of fun if you're the type of Priest/Bishop who isn't just standing in one spot spamming, but is up and down ropes a lot. I found it handy for not getting knocked off ropes by Skeles' magical attack while chasing and HSing party members!
Uh, wasn't making any judgments lol! It's simply that Doom is most useful for Priests/Bishops who are on the move and up and down ropes a lot as it stops you from getting knocked away when you're trying to get on/up a rope!
