I am still trying to be nice so .... dont hate me if sometimes my explanation seems to be rude
Adventurer, you cant consider that as Buff bonus for him
He needs completly remake. If no higher dodge chance, then bonus HP so that they can start doing what they were supposed to do, block sectors. If not, then bonus aim in FF so that they can become good dmg.
Builder honestly depending on how high level you are, higher level means more useless as it comes to this change or whatever you name it. You can take santa and you will dodge if you are level above 160 and you will dodge good number, not the best but good enough to protect players behind you. If somebody wants to do church and has everything in building, you can take basic Cortina set and you are good to go because of his bonuses. Simple.
After that short time of dueling, dueling would not be fair. Sure you could take soldier with his tactics and huge hp down with higher chance if you take more duelers with you, but to other characters it would be totally unfair.
Soldier is topic on its own. Or bonus hp, or bonus tactics, not both. Thats the problem nowdays with dueling sets, they have both meaning soldier is op in duels.
Crit rate 2% for everybody? Now tanks are struggling and are beaten by low levels because they dont hit you 30 rounds but once they do, its probably a crit. That would be good adition to servers where bug Forts are full during fight and you need to take that hp down. But most of the servers are dead and cant even fill small fort up, so, no. not a good idea.
Each character should have FF bonus only if on the own tower. If you move to other sector, tower, building whatever you should loose that bonus. So that everyone has the same bonus, its better for attackers they may see hope in this system and ff would be playable more than now. Or at least reduced bonus if not on its own tower.
I was one of those complaining about this nonsens changes and i stand behind it still.
