Before you immediately shout "This defeats the purpose of PvP, you noob!!" and raze my thread for heresy, here's a "Cons and Pros" list for my proposal.
Cons
- This somewhat mitigates the functionality and purpose of the automatic "faction lock" when the population is significantly heavier on one side or the other.
- This will probably have no effect on a majority of players wanting to make and play Alliance Paladins.
- As is currently the case on the ("RP-")PvE realm, this does allow an opposite-faction player to "curse you out", which may add to one's stress.
- On that same note, this also means that players from opposite factions can "stalk" each other across the world via Friends List, as is also the case on the ("RP-")PvE realm.
- "This defeats the purpose of PvP, you noob!!"
- To be more specific, this arguably defies the lore of the Alliance and Horde being in a state of "Cold War", or being outright hostile toward one another.
- This somewhat mitigates the "faction lock" issue as Shamans can join Alliance parties and Paladins can join Horde parties.
- No separation anxiety!: friends can be in the same parties and guilds regardless of faction.
- It's more fun to trash-talk your opposite-faction opponents when you can understand each other. (;
- This actually doesn't prevent people from engaging in World PvP, much less Battleground PvP. Even players in the same guild can still kill each other and do Battlegrounds, if they want to.
- This doesn't really affect the lore as PvP is purely a game mechanic. Lore-wise, the Alliance and Horde are un an uneasy kind of "Cold War" with isolated land or resource conflicts popping up. It's actually more lore-friendly for, say, an Orc Warrior and a Human Paladin to become allies and possibly friends.
- Additionally, the Common / Orcish language split was purely a game mechanic. Lore-wise, every sentient race on Azeroth should know "the common language".
