The issue of FPs donation is not a minor thing Lord B,
Yes its nice to be able to spend FPs faster but not this umbalanced way 10FPs at a time on browserwith refresh between each and for Apps user no limit of the amount they can put in one time with as HRC pointed no risk at all for them , if more then one try to snipe at the same time you are safe as your device will just go in error, absolutely scary.
I have seen a player in my world doing the run over GB sniping on purpose to other peoples and twice to myself its not just a minor thing to loose a thousand FPs that way. As it becomes known , more and more players will do it and it will become totaly unsafe to add your FPs from a browser.
There are very easy alternatives to add points fast , for example we could have a add 100FPs key as well as the add 10 and add 1 but it should be 1 click at a time for everyplatforms not this feature only available at the moment to mobile users to total all points on your device before the package is sent In one time.
AS you said HRC there are many diferent features between the mobile apps and the browser and it is quite understandable, a mobile device will never have the same processing power as a PC so is limited in the number of feature it can run
Some of the diferences you mention are certainly annoying but in my view do not realy change the nature of the game and overall the game run smoothly on mobile apps . Still the issues I highlighted not only impact heavily on the fairness of the game but they could also be easily solved if someone at Inno took some time to look into it
(Yes I know GvG on mobile will never happen unless specs of mobile devices were well above what they are for the moment, if anyone knows were I can found an official answer from the devs on that matter could you be kind enough to direct me to it)
