I have been here for over 10 years and perhaps I am unable to adapt.
You have been around long enough to qualify as one of "those old guys". Trust me, I've been there, long ago
The Wagon Wheel manufacturers were pretty well bent out of shape when the rubber tire was made, and the wagon wheel users were upset because they had to change, but things do evolve for a reason. My mustang won't run well on wooden wheels and I'm just flat out ok that the wagon wheel industry faded away. It'll be fine. Remember, way back when, we were flying around in cartoon planes that were state of the art and high tech as could be, we were even proud we had full color, both black and white! Then, those darned 256 color games came out and it was just too hard on the eyes. Well we got used to it. Then, good grief that was just almost too much when the 3D element arrived and we couldn't count the 24 pixels that made up the wing and they really started going nuts.
You will adapt, if you want to. If not, you won't. But just don't forget that HTC designs the game for those who want to be here, not those who want to leave. The game has to evolve, and sometimes that means old things have to be scrapped to lay the groundwork for an entirely new direction. At one point, the start of a design reaches the best it can be and it cannot be improved upon any longer, it must start new and evolve to the next level. The game is going to evolve, some will continue, some won't, and new players will come along, old players will stay and some will leave. It is what it is. But, this isn't just a game you adapt to, it's an environment you belong to.
Will you toss out your favorite bar if they change the bar stools that you found comfortable for the past 10 years but the legs keep falling off? Move to a new house if the old recliner just didn't hold up anymore and it was time to get a new one? Even if the new one had the handle on the left side instead of the right?
This is a home, feel free to go to another game and try and start building the camaraderie you have built here in the past few years. Guess what? You are going to have to learn a new interface anyway. Aren't you? What are you leaving? The people you have met over the years because you have to learn a new way of playing, when leaving means you play something else, lose the friends and still have to learn a new way of playing?
Silly? Ya, but that's just my opinion and it would be a shame to see you leave, but if you do that's just the way it goes.
