This is a good first step... and I have no doubt this is only the first step. This seems to solve the issues people had with HO stealing. Nothing wrong with that.
As for the issue of people leeching by standing at the zone entrance not helping in a team... kick them, put a range limitation in, whatever... this is a minor issue at best.
With all the discussion HOs have generated, you can be sure the devs are listening and I'm sure they are not yet done with their mods in regards to HOs.
I fully expect we will at some future patch we will be able to tell who has HOs and who does not so we can choose arena opponents based on if they have them or not.
I have not done and HO raid, I may do it once just to say I did it, but IMO HOs have broken this game by introducing "loot" since loot is not a concern at any other point. No biggie when it was only a PvE game, but with PvP, even with this fix, people will farm Hami over and over until they do get HOs in everything. Count on it - its the nature of most wanting to be competitive in PvP.
Since I fully expect to be able to choose my opponents in the arena based on them having HOs or not, HOs concern me little at this point. However, how will this be handled when CoV comes out? Will HO'd Heros be able to fight non HO'd (equivalent) villians?
I personally think HOs should just be scrapped... with PvP, Hami no longer needs to be the end game, and HOs are no longer required as the carrot to get you to do it. PvP is the end game for many of us. For those that do not see PvP as the end game, good immersive content is what they need - not unbalancing HO carrots.
I started playing CoH only after I knew plans for PvP were on the table - pvp is my end game - and I don't want to have to farm "uber lewtz" to do it. Grinding to 50 is enough tyvm; no need to screw up an otherwise unique MMORPG model by introducing loot so late in the game.
I leared from DAOC that needing to farm uber loot to be successful in PvP is a very very bad thing for anyone that has a life away from their computer.
