The change to 'stacking' helps negate a couple exploits in game and minimize the advantage of others. This change has been done before, back in like 2012 or so ( i forget the exact year). Gladiators have the exact same number of skills we had since then, despite a cap 25 lvls higher.
The reason people are upset is due this change slowing down the pace of the game. It also reduces potential damage output in an already pay2win game. This game's been around for 12 years now, and no other game gave us a mechanic like 'stacking'. Usually auto attacks in other MMO's mean next to nothing, but in Fiesta it was the corner stone of an entire group of classes.
So to counter the negative implications of this change, I would suggest a minor buffs in attack speed to bring the pace of the game back up. We recover some of our damage output, have a more enjoyable combat pace but still retain the positive aspects of the recent patch.
Axe base attack speed: 1.5 --> 1.3 (0.2 sec across the board)
2h Sword base attack speed: 1.3 --> 1.1 (0.2 sec across the board)
1h sword attack speed: 1.0 --> 0.9 (0.1 sec across the board)
Violence : Add a new lvl up at 120 which reduces attack speed by an additional 0.1sec and increase the DOT damage of violence.
Claws base attack speed: 1.6 --> 1.4 (0.2 sec across the board)
Dual sword base attack speed: 1.8 --> 1.6 (0.2 sec across the board)
Blade "That sword which is too cool for this class" base attack speed: 1.0 --> 0.9 (0.1 sec across the board)
Bow base attack speed: 1.1 --> 1.0 (0.1 sec across the board)
Crossbow base attack speed: 1.4 --> 1.3 (0.1 sec across the board)
Keep in mind lvl 50 blue weapons, 70 blue weapons, UT weapons have lower attack speed. So UT axe 1.3 --> 1.1 sec.
Everyone is upset about the gameplay, implement a positive change to counter the negative. The skill re-balancing was nice, but it was nowhere enough.
