Yes i also believe this is the reason. However, from a personal standpoint you think that 25 milliseconds is negligible. That is YOUR preference from a standpoint of numbers with no practical consideration, i have played templar long enough to know that 18% drop in att speed is significant from 30%. Templars are 18% slower at lvl 7 blunt when compared to previous 30%. FULL STOP. now they are only 12% faster at lvl 7. there is no maths involved just percentage according to the skill.
Which reminds me, let me see how you came up with your numbers. 25ms sounds VERY doggy. 18% slower is 25ms? SHOW ME YOUR CALCULATION hahahaha
