Elite instances are never a bad idea; Gives you a chance to farm out new ninjas and strengthen those you currently have. Hinata/sasuke are never a bad bet to continue to grind out everyday. So as a f2p it really depends on your main who you want to grind out to work with your team, but hinata is always a good return for your grind. Guy can be great for your team in both pvp and pve with his leech for your team and interupt plus his stats buffs.
As for you coupons it's always best to save them for a favorable event which changes every Thursday and last a week, just be patient it may take a month or 2 of saving your coupons for them to reward you with something in an event. For instance Iruka is a very good ninja, he's in this weeks event and if you have the chance to snag him at 24coupons/fragment, thats 720coupons to recruit him(2stars). And well worth it. So be patient and if you're unsure if a current event is worth you spending your coupons c*ways refer here for insight on whether it is or not for a f2p player.
As per your group contributions It may vary from person? I personally would max my ninj/attack/*ion's first then work on life/res/def and then whatever is left. Donate max everyday! Then whateever is left upgrade your equipment.
As for the vendors it's whatever your preference is once again, while they may be cheaper in future shop updates it just means itll be even longer til you have that ninja if you're going to wait, so when push comes to shove currently its a tobi hype train and he's very good paired with hinata and someone who can repulse. Kabuto is a * good healer and generally used in most PVE content*cough* Strong Approaching* His clones and heals are undeniably the best and worth the buy. While this last one is utterly and completely preference, if you want to sacrifice the need not to get any ninjas in group/ranked shop you can obtain medium refine/low refines... Start stocking up at L60 they becomes super relevant for PvP, not that they aren't always so I'd just say get ahead of the game, just a forewarning it is expensive no matter how you look at it and as f2p this is the easiest way I'd believe.(Just start once you've got the ninjas you want or have spare coins)
As for your stamina it can be partially used on elite instances to grind out ninjas you want. If you can do strong approaching(When you reach of level of course), get it out of the way so you can grind out your battle armor to rank 3 and get your level up in it. And use the remaining stamina to grind out your mats for upgrading your equipment.
As A final reminder, I would recommend saving ALL of your seal scrolls until the L80 Treasure is released in a future update. while you may be behind now, when the meta changes and shifts possibly with Kage treasure when its released it'd be better to dip your hands into that treasure with far more relevant ninjas then wasting your time with ninjas who wont be viable anymore(Not to say they wont, but personally I believe it'd be the smartest move) and just use your free pulls and you're still bound to get something nice sometimes down the road. This will be the greatest testament to your patience and self ability to hold yourself back.
To add to the final reminder SAVE all your stamina pots for a thursday event that will be worthwile for a good ninja you can grind out purely on stamina. I have around 220stamina potions and 100 (10stamina) potions sitting around just for that cause right there. I know some people will say save them for monday expierence days, but truley... all you're getting x2 exp on missions so as a f2p youll be getting 3k instead of 1500exp per an instance sweep.... In the end it's not even worth it, You'll be stuck at the level waiting spots like everyone else and eventually be stuck at level cap... where as you couldve jsut saved them been patient on levels and gotten a kickass ninja out of it(And once again if you're unsure of stamina events and not sure if it's time to * your stam pots ask here and will help you to insure if its a green or red light to start drinking those pots)
