The following text is a copy paste job from my reply to another thread, so some things might appear out of context.
A couple of things. I've been outdriving R11s drivers with that "not so good" R11 on many occasions, or at least go toe to toe with it. The same way that anyone who actually knows where to aim drives and what spin to use can easily outdrive both R11s with a L81 G20. And even if you don't, it's less than 1 size iron difference in the end, so no biggy. Bigger problem for lower levels are irons, although after L79 the Bladez even the field enough for anyone with skill.
That new driver isn't really that hot, especially on courses where a higher trajectory works better. i'd much prefer the R11s (2 more levels for me). And the slower meter could backfire. 1 degree of difference in speeds between the driver and irons is bad enough, but to add 1 more?
I only see 1 potentially huge issue with the new gear and that's the L48 driver. Placing it there is like asking people to restart or multiaccount. Like we don't already see enough of that, now it's been made even easier. Imagine some current or former legends coming out as hacks, only needing to get to L48 (lightning quick to get there) and having a 275y driver combined with low level R11s and CGs. Peachy.
Edit: And the reason why it's good the new club is at L98 is this (another copy paste)
If you're gonna compare this to real life, you can compare it this way. More XP points mean more playing time and practice. More practice usually brings better results in real life. WGT basically rewards your "practice" time with better ability, the same as it would be better in real life. They can only do it with more power, precision and forgiveness, which could only come after a lot of time playing in real life.
I hope I expressed what I mean clear enough. Basically, if you only played for 3 months IRL, your game would have a disadvantage to someone who's played for 3 years most times, right? But because WGT can't really enhance your actual ability, they do it by offering long time players a chance to get enhanced clubs.
