A producer's letter was posted for Warhammer Online today. In it, Jeff Skalski reveals some of the Warhammer Gold development team's plans for 1.3.0b, a patch planned for release this month (and to go on the Public Test Server within a week.)

Updates in the patch will include:

All AoE abilities are moving to standardized ranges and coverage, based on their type (Melee "Cleave", Conical AoE, Line AoE, PBAoE, or Targeted AoE).
All Immunities Persist Through Death: Pretty simple one here, no more Stun -> Dead -> Rez -> Stun -> Dead.
Increased Duration of Disable Immunities: Immunities for the disable family of CC (knockdown, stun, disarm, and silence) will have their immunity timers increased from 6 times the effect duration to 10 times the effect duration. In other words, if you are stunned for three Warhammer Gold, in 1.3 you would have an 18-second immunity. With this change, that same immunity would be 30 seconds.
Root Immunity and Knockback/Pull Immunity Combined: We're rolling root immunity and knockback/pull immunity together into a single "movement immunity" effect. This immunity will remain for 30 seconds, and will prevent you from things such as being pulled in, then immediately rooted in place, making it a much more tactical decision about whether it's better to stop an enemy in place or move them around.
New Renown Purchase Ability: We are releasing a new Renown Point purchasable ability at Renown Rank 40 that will be a "CC immunity" that players can trigger for temporary CC immunity. This should help break up the "I get CC'd at the beginning of a fight and there is nothing I can do about it" issues.
The next phase of Archmage and Shaman changes, including cohesive Mastery paths and new abilities and Tactics.
Runes and Marks will be able to stack on allies.
Players will now receive an additional 50% bonus to experience and a 150% bonus to renown when killing players near Battlefield Objectives or Keeps in open RvR.
Dozens of bug fixes.
