@RenoRick:
Understand your reluctance to spend any money, but for the better part the frustration comes from that side, given your situation as a Master with very basic clubs.
ad 1) Rough & Bunker shots with the Starter wedges were frustrating to me, too. Hint: Get a custom 64° wedge (+ a 60°) for much better results. L28 Cleves, or L39 ATVs.
ad 4) More spin comes with better clubs and better balls, and it's only perfect with top equipment. That is, long iron shots stopping on the dime (really!) and wedge shots that zzzip back to your feet (literally).
These items are talkative about the difference between playing for free and paying for more fun and better scores - all at your hands!
ad 2) I agree, it's less than perfect at times. This is the price we have to pay for the HD photo displays all over, and I gladly pay it. Other than in the real game, different views are available at a mouseclick, and with some experience (you're level 80!) it's dispensable - you know your aim, your club, the meter power - get it going!
ad 3) These are the built-in variations - sometimes harsh but we have to bear them.
There are other flaws which take away some fun of the game, discons, meter jumps and whatnots - nevertheless, ev1 has to decide if it's fun and leisure enough to invest some.
