This is going to be quite a long post so please stick with me. I am new to the summoner job and so far I've been trying to read all about the job and take in any knowledge I can about playing it so as I don't completely embarrase anyone else who is also smn. I have known since I started trying to get the job that untill about level 70 I can pretty much expect to heal the party as either a main or backup which I can deal with as I started to love my whm job and role as healer.
However I am not completely sure about what I should be doing in parties at this level (Im level 16). I know that once I get more summons they will have BPs that can cure and buff the party and so I should summon, BP and release but as I only have carbuncle I am unsure of what to do. Now I know that carbuncle has the very helpful Healing Ruby BP but when I was in a dunes party I was main healing and I found that by the time I had summoned carbuncle to use healing ruby, the party had suffered quite a bit of damage and I had lost a pretty big bit of my mp and was usually better of just sticking with cure I :(
So can anyone tell me if this is just me being a really bad summoner and I should be able to work out how to deal with summoning and curing more effectively or is it just tough at this level? I just don't want to have to move onto Qufim Island and completely suck at my job and get everyone killed.
