Next time you want to try and point out what you think is stupid, I suggest that asking what I meant first, instead of quoting me out of context and posting things that I'm just going to make you look stupid on.
Sorry, I am not smart enough to follow your argument.
Not even close. A character with 5 Speed and Glass Cannon has as much recovery AP as a character with 17 Speed. 7 Speed + GC is roughly equivalent to 21 Speed. Those are stupidly high numbers, and all GC asks in return is that you throw some points in Constitution instead. Considering the massive savings in Speed, that's no problem. If you take your previous Speed investment, toss it in Constitution instead, and take GC, you will have a stronger character every single time.
Not sure, but I think you would need to crunch the numbers on this one. I'm not saying that GC isn't overpowered, but let's think about the 5 SPD + GC vs. 17 SPD scenario (assuming your calculations that these are equivalent is correct), and just the recovery AP and HP tradeoff.
On hard mode (ignoring LW for now), GC would give you 25% base HP (-25% from hard, -50% from GC). To re-coup the HP effects, you would need to triple your base vitality through constitution boosts. From our lovely discussion on constitution and vitality (assuming you have 7 CON given 5 SPD), you would need approximately 10 more points into constitution to get back at your starting HP. Throw in the 2 attribute points you can trade in for not taking GC, this is almost equal in attribute points, HP, and recovery AP. The difference (and overpoweredness, arguably) lies in max AP, which you have in the GC + constitution build but not in the flat 17 SPD build. This is also discounting, again, other benefits of speed (movement, starting AP) and additive effects, such as picture of health, lone wolf, etc.
Another point is that HP isn't even all necessary if you shield, position, and CC appropriately. Not sure what I'm trying to conclude here, but just throwing out a bunch of data.
