Ive been personally really enjoying the beta so far, however theres alot of things that have been bothering me with the combatsystem. Its overall a really good concept and I think it shows alot of promise. I realize that nerfing and buffing heroes will never end up being completely fair and nerfs always makes someone disapointed thats why I think focusing more on balancing the moves every hero has incomon such as dodge and Guard Break would be much more effective.
I think that right now the Guard Break is just a little bit to easy to execute and very hard to block benefiting heroes like the vikings alot. To solve this issue removing the autolocking/aimbot system that occurs when trying to dodge a Guard Break will make it easier for heroes like the peacekeeper to dodge them. I also think just giving people a little bit more reaction time when trying to block a Guard Break would be helpful as reaching for the MMB in the middle of a fight is quite tricky. Could also help letting people bind guard break and guard break block to different keys.
Overall I have been getting frustrated especially with the Warlord, how hard it is to see its attacks and how easy it is to spam with. Comparing it to other heroes its moveset is filled with moves that can benefit you in a fight while other heroes are left with just a few. However I understand that its a beta and all but I think that the things listed above would really help balance out the warlord aswell as many other heroes.
