I like playing as an Engineer (only when there's enemy vehicles, else I favour Assault or Support—personal subjective option). It is good fun, but here some thoughts offered:
○ reload times for anti-vehicle munitions ought to be faster, now that vehicles have been buffed — it is agonising to see our character moving their arms and legs to reload only to end up bandaged, because the vehicle was so much faster in firing and so much slower in losing health — now that we have to expose ourselves more often;
○ anti-tank mines ought not to be made visible to tank drivers, neither to enemy infantry — only the co-driver should be able to spot and disable them.
Apart from that all good, and yes, it was a good idea to simplify damage areas and their percentages: more damage in the back and less in front, with sides in-between.
