Since NO GM/Dev is responding to this thread. Let's take guesses. Crit % is really just a % of a %. Make sense? The random rolls you do....sometimes you are beyond lucky rolling 70 to 100 on a normal /ran 100 roll 8 or 10 times in a row. Sometimes, you consistently roll low. Also, maybe, the % you have, say 31% after adding it up, really isn't 31% because you don't add those percentages. Maybe they are averaged out which would make your actual crit chance a MUCH smaller than 31% chance.
Hurray for the guessing game!
I am going to try really hard to explain things without just totally bashing you, but please understand that you simply have very little understanding of what you are talking about (in this and many other threads), and it causes people to regularly flame you and derail threads you post in. Let me try to explain things point by point.
First, crit % being a % of a % goes against all the literature/data/dev information posted about critical spells up until this point in time. So, no, it makes no sense. Critical spell chances may be applied separately, instead of all together, which would slightly lower the over all crit rate.
I dont get the point you are making about rolls. That is how all random chance events work. This is why we parse together hundreds of spell casts, to get an average. If i fight one mob, maybe my crit rate is super low or super high because of random chance. If I fight 100 mobs, it will average out, and better represent my real crit chance.
The concept of averaging out crit % chances makes absolutely zero sense. If this was the case, characters that did Tome of Critical Evocation, or Tome of the Mind would get *weaker* because they provide a lower crit bonus than other sources. It just makes absolutely zero sense for crit rate to work like this.
I've played a wizard for about 5 years now. For 4 of those years, my crit rate was approximately equal to the addition of my individual crit bonuses. Now I come back, and play for a week, and it is substancially different. Other players notice this difference and make posts about it. Additionally, there seem to be substantial crit rate differences between zones.
All of these factors indicate there are some major bugs present. The fact that a recent patch said something like "spell crits should be working more normally again" indicates devs are aware of the problem, and attempting to fix it. If this was some intended change, it makes absolutely zero sense, to randomize caster dps by zone, totally gimping us in some places, and changes that substantial are almost always posted in patch notes.
In conclusion, this is very clearly a bug. Your posts make no sense and show a very poor understanding of the mechanics being discussed, and it is really frustrating to try to have a reasonable discussion and gather data when you clutter it up with post after post that adds nothing to the discussion. Please just stick to posting in threads where you have a thorough understanding of the topics being discussed.
Thank you.
