We prove that all wild blocks of type A Hecke algebras with quantum characteristic e \geqslant 3 -- i.e. blocks of weight at least 2 -- are strictly wild, with the possible exception of the weight 2 Rouquier block for e = 3. As a corollary, we show that for e \geqslant 3, all wild blocks of the q-Schur algebras are strictly wild, without exception.
