I'm playing a strength build :C
You are playing borderline STR shielder build if you're having 27 STR. For 2H builds 30 is minimum for STR builds imho. Actually I believe it is 33 STR and I'll explain why.
Before the patch that buffed AGI, STR builds had no real downfall and AGI builds were inferior but properly balanced. Before that patch, AGI builds had strong points and weaknesses compared to STR builds which didn't have any weaknesses due to free wpf. Right now tables turned and AGI builds have almost no weakness while STR builds lost the swing speed which is very important. Notice that I'm talking about extremes, known as AGI and STR builds. Between are balanced builds which were decent but are always losing to the better extreme of a period.
Before, when most were level 30 and high levels were around level 34, AGI builds were identified as lower than 15 STR for standard levels and lower than 18 STR for high levels (24+ AGI). Between 18 and 24 STR for regular and high levels were balanced builds and above 24 STR, but that was hard to determine because as I said STR builds had no real weakness.
Now situation is different completely. Level are higher and anything above 15 AGI is considered as AGI build because it gives you enough wpf to be able to swing fast enough. For example, at level 36/37 which is common these days you can have 30/18 build with 155 wpf. Moves fast enough, swings fast enough, in medium armor speed bonus is decent, pure PS is high. Hits like a truck, can survive a lot of hits. Should be a STR build, but resembles balanced more and has no weakness.
That's the main problem, first was STR op now is AGI. Extremes must have one strenght and one weakness. Can't have both.
At 33 STR you can have realistically 12 AGI tops, when you start to feel lack of wpf and reduced swing speed compared to other players who are mostly AGI. I know they are AGI because this mod is currently S key fest and only AGI builds S key a lot. As a extreme STR build (previous two builds 36/9, 42/3 and now 45/3) I seldom press S key because I'm too busy with catching everybody who backpedal from me (I'm holding W key).
Also would like to say it again, it is a big mistakes making STR and AGI stats equal. That only creates issues with speed bonus (which is tailored for native AGI values, not off the charts cRPG values). AGI must be support stat, nothing more.
