One of the most commented features of 4.10 has been the 2s bomb arming delay. We have listened to your feedback and spent a lot of time and energy reviewing and discussing this feature inside our team. In 4.101 we have removed arming delay from ampoule loadouts only. In 4.11 - we will rework the arming delay for each individual bomb based on available historical references and within limitations of IL-2 code. Plus we will make this feature optional either via an existing or a new difficulty switch.
